+version 2.90
+	Fix reversion in --rev-server introduced in 2.88 which
+	caused breakage if the prefix length is not exactly divisible
+	by 8 (IPv4) or 4 (IPv6).
+
+	Fix possible SEGV when there server(s) for a particular
+	domain are configured, but no server which is not qualified
+	for a particular domain. Thanks to Daniel Danzberger for
+	spotting this bug.
+
+	Set the default maximum DNS UDP packet sice to 1232. This
+	has been the recommended value since 2020 because it's the
+	largest value that avoid fragmentation, and fragmentation
+	is just not reliable on the modern internet, especially
+	for IPv6. It's still possible to override this with
+	--edns-packet-max for special circumstances.
+
+	Add --no-dhcpv4-interface and --no-dhcpv6-interface for
+	better control over which inetrfaces are providing DHCP service.
+
+	Fix issue with stale caching: After replying with stale data,
+	dnsmasq sends the query upstream to refresh the cache asynchronously
+	and sometimes sends the wrong packet: packet length can be wrong,
+	and if an EDE marking stale data is added to the answer that can
+	end up in the query also. This bug only seems to cause problems
+	when the usptream server is a DOH/DOT proxy. Thanks to Justin He
+	for the bug report.
+
+	Add configurable caching for arbitrary RR-types.
+
+	Add --filter-rr option, to filter arbitrary RR-types.
+	--filter-rr=ANY has a special meaning: it filters the
+	answers to queries for the ANY RR-type.
+	
+	Add limits on the resources used to do DNSSEC validation.
+	DNSSEC introduces a potential CPU DoS, because a crafted domain
+	can force a validator to a large number of cryptographic
+	operations whilst attempting to do validation. When using TCP
+	transport a DNSKEY RRset contain thousands of members and any
+	RRset can have thousands of signatures. The potential number
+	of signature validations to follow the RFC for validation
+	for one RRset is the cross product of the keys and signatures,
+	so millions. In practice, the actual numbers are much lower,
+	so attacks can be mitigated by limiting the amount of
+	cryptographic "work" to a much lower amount. The actual
+	limits are number a signature validation fails per RRset(20),
+	number of signature validations and hash computations
+	per query(200), number of sub-queries  to fetch  DS and DNSKEY
+	RRsets per query(40), and the number of iterations in a
+	NSEC3 record(150). These values are sensible, but there is, as yet,
+	no standardisation on the values for a "conforming" domain, so a
+	new option --dnssec-limit is provided should they need to be altered.
+	The algorithm to validate DS records has also been altered to reduce
+	the maximum work from cross product of the number of DS records and
+	number of DNSKEYs to the cross product of the number of DS records
+	and supported DS digest types. As the number of DS digest types
+	is in single figures, this reduces the exposure.
+
+	Credit is due to Elias Heftrig, Haya Schulmann, Niklas Vogel,
+	and Michael Waidner from the German National Research Center for
+	Applied Cybersecurity ATHENE for finding this vulnerability.
+
+	CVE 2023-50387 and CVE 2023-50868 apply.
+	Note that the is a security vulnerablity only when DNSSEC validation
+	is enabled.
+	
+	
+version 2.89
+        Fix bug introduced in 2.88 (commit fe91134b) which can result
+	in corruption of the DNS cache internal data structures and
+	logging of "cache internal error". This has only been seen
+	in one place in the wild, and it took considerable effort
+	to even generate a test case to reproduce it, but there's
+	no way to be sure it won't strike, and the effect is to break
+	the cache badly. Installations with DNSSEC enabled are more
+	likely to see the problem, but not running DNSSEC does not
+	guarantee that it won't happen. Thanks to Timo van Roermund
+	for reporting the bug and for his great efforts in chasing
+	it down.
+
+
+version 2.88
+	Fix bug in --dynamic-host when an interface has /16 IPv4
+  	address. Thanks to Mark Dietzer for spotting this.
+
+	Add --fast-dns-retry option. This gives dnsmasq the ability
+	to originate retries for upstream DNS queries itself, rather
+	than relying on the downstream client. This is most useful
+	when doing DNSSEC over unreliable upstream networks. It comes
+	with some cost in memory usage and network bandwidth.
+
+	Add --use-stale-cache option. When set, if a DNS name exists
+	in the cache, but its time-to-live has expired, dnsmasq will
+	return the data anyway. (It attempts to refresh the
+	data with an upstream query after returning the stale data.)
+	This can improve speed and reliability. It comes
+	at the expense of sometimes returning out-of-date data and
+	less efficient cache utilisation, since old data cannot be
+	flushed when its TTL expires, so the cache becomes
+	strictly least-recently-used.
+
+	Add --port-limit option which allows tuning for robustness in
+	the face of some upstream network errors. Thanks to
+	Prashant Kumar Singh, Ravi Nagayach and Mike Danilov,
+	all of Amazon Web Services, for their efforts in developing this
+	and the stale-cache and fast-retry options.
+
+	Make --hostsdir (but NOT --dhcp-hostsdir and --dhcp-optsdir)
+	handle removal of whole files or entries within files.
+	Thanks to Dominik Derigs for the initial patches for this.
+
+	Fix bug, introduced in 2.87, which could result in DNS
+	servers being removed from the configuration when reloading
+	server configuration from DBus, or re-reading /etc/resolv.conf
+	Only servers from the same source should be replaced, but some
+	servers from other sources (i.e., hard coded or another dynamic source)
+	could mysteriously disappear. Thanks to all reporting this,
+	but especially Christopher J. Madsen who reduced the problem
+	to an easily reproducible case which saved much labour in
+	finding it.
+
+	Add --no-round-robin option.
+
+	Allow domain names as well as IP addresses when specifying
+	upstream DNS servers. There are some gotchas associated with this
+	(it will mysteriously fail to work if the dnsmasq instance
+	being started is in the path from the system resolver to the DNS),
+	and a seemingly sensible configuration like
+	--server=domain.name@1.2.3.4 is unactionable if domain.name
+	only resolves to an IPv6 address). There are, however,
+	cases where is can be useful. Thanks to Dominik Derigs for
+	the patch.
+
+	Handle DS records for unsupported crypto algorithms correctly.
+	Such a DS, as long as it is validated, should allow answers
+	in the domain it attests to be returned as unvalidated, and not
+	as a validation error.
+
+	Optimise reading large numbers of --server options. When re-reading
+	upstream servers from /etc/resolv.conf or other sources that
+	can change dnsmasq tries to avoid memory fragmentation by re-using
+	existing records that are being re-read unchanged. This involves
+	seaching all the server records for each new one installed.
+	During startup this search is pointless, and can cause long
+	start times with thousands of --server options because the work
+	needed is O(n^2). Handle this case more intelligently.
+	Thanks to Ye Zhou for spotting the problem and an initial patch.
+	
+	If we detect that a DNS reply from upstream is malformed don't
+	return it to the requestor; send a SEVFAIL rcode instead.
+
+	
+version 2.87
+        Allow arbitrary prefix lengths in --rev-server and
+	--domain=....,local
+
+	Replace --address=/#/..... functionality which got
+	missed in the 2.86 domain search rewrite.
+
+	Add --nftset option, like --ipset but for the newer nftables.
+	Thanks to Chen Zhenge for the patch.
+	
+	Add --filter-A and --filter-AAAA options, to remove IPv4 or IPv6
+	addresses from DNS answers.
+
+	Fix crash doing netbooting when --port is set to zero
+	to disable the DNS server. Thanks to Drexl Johannes
+	for the bug report.
+
+	Generalise --dhcp-relay. Sending via broadcast/multicast is
+	now supported for both IPv4 and IPv6 and the configuration
+	syntax made easier (but backwards compatible).
+	
+	Add snooping of IPv6 prefix-delegations to the DHCP-relay system.
+
+	Finesse parsing of --dhcp-remoteid and --dhcp-subscrid. To be treated
+	as hex, the pattern must consist of only hex digits AND contain
+	at least one ':'. Thanks to Bengt-Erik Sandstrom who tripped
+	over a pattern consisting of a decimal number which was interpreted
+	surprisingly.
+
+	Include client address in TFTP file-not-found error reports.
+	Thanks to Stefan Rink for the initial patch, which has been
+	re-worked by me (srk). All bugs mine.
+
+	Note in manpage the change in behaviour of -address. This behaviour
+	actually changed in v2.86, but was undocumented there. From 2.86 on,
+	(eg) --address=/example.com/1.2.3.4 ONLY applies to A queries. All other
+	types of query will be sent upstream. Pre 2.86, that would catch the
+	whole example.com domain and queries for other types would get
+	a local NODATA answer. The pre-2.86 behaviour is still available,
+	by configuring --address=/example.com/1.2.3.4 --local=/example.com/
+
+        Fix problem with binding DHCP sockets to an individual interface.
+	Despite the fact that the system call tales the interface _name_ as
+	a parameter, it actually, binds the socket to interface _index_.
+	Deleting the interface and creating a new one with the same name
+	leaves the socket bound to the old index. (Creating new sockets
+	always allocates a fresh index, they are not reused). We now
+	take this behaviour into account and keep up with changing indexes.
+
+	Add --conf-script configuration option.
+
+	Enhance --domain to accept, for instance,
+	--domain=net2.thekelleys.org.uk,eth2 so that hosts get a domain
+	which relects the interface they are attached to in a way which
+	doesn't require hard-coding addresses. Thanks to Sten Spans for
+	the idea.
+
+	Fix write-after-free error in DHCPv6 server code.
+	CVE-2022-0934 refers.
+	
+	Add the ability to specify destination port in
+	DHCP-relay mode. This change also removes a previous bug
+	where --dhcp-alternate-port would affect the port used
+	to relay _to_ as well as the port being listened on.
+	The new feature allows configuration to provide bug-for-bug
+	compatibility, if required. Thanks to Damian Kaczkowski 
+	for the feature suggestion.
+
+	Bound the value of UDP packet size in the EDNS0 header of
+	forwarded queries to the configured or default value of
+	edns-packet-max. There's no point letting a client set a larger
+	value if we're unable to return the answer. Thanks to Bertie
+	Taylor for pointing out the problem and supplying the patch.
+	
+	Fix problem with the configuration
+	
+	--server=/some.domain/# --address=/#/<ip> --server=<server_ip>
+
+	This would return <ip> for queries in some.domain, rather than
+	forwarding the query via the default server.
+
+	Tweak DHCPv6 relay code so that packets relayed towards a server
+	have source address on the server-facing network, not the
+	client facing network. Thanks to Luis Thomas for spotting this
+	and initial patch.
+
+
+version 2.86
+	Handle DHCPREBIND requests in the DHCPv6 server code.
+	Thanks to Aichun Li for spotting this omission, and the initial
+	patch.
+
+	Fix bug which caused dnsmasq to lose track of processes forked
+	to handle TCP DNS connections under heavy load. The code
+	checked that at least one free process table slot was
+	available before listening on TCP sockets, but didn't take
+	into account that more than one TCP connection could
+	arrive, so that check was not sufficient to ensure that
+	there would be slots for all new processes. It compounded
+	this error by silently failing to store the process when
+	it did run out of slots. Even when this bug is triggered,
+	all the right things happen, and answers are still returned.
+	Only under very exceptional circumstances, does the bug
+	manifest itself: see
+	https://lists.thekelleys.org.uk/pipermail/dnsmasq-discuss/2021q2/014976.html
+	Thanks to Tijs Van Buggenhout for finding the conditions under
+	which the bug manifests itself, and then working out
+	exactly what was going on.
+
+	Major rewrite of the DNS server and domain handling code.
+	This should be largely transparent, but it drastically
+	improves performance and reduces memory foot-print when
+	configuring large numbers domains of the form
+	local=/adserver.com/
+	or
+	local=/adserver.com/#
+	Lookup times now grow as log-to-base-2 of the number of domains,
+	rather than greater than linearly, as before.
+	The change makes multiple addresses associated with a domain work
+	address=/example.com/1.2.3.4
+	address=/example.com/5.6.7.8
+	It also handles multiple upstream servers for a domain better; using
+	the same try/retry algorithms as non domain-specific servers. This
+	also applies to DNSSEC-generated queries.
+	Finally, some of the oldest and gnarliest code in dnsmasq has had
+	a significant clean-up. It's far from perfect, but it _is_ better.
+
+	Revise resource handling for number of concurrent DNS queries. This
+	used to have a global limit, but that has a problem when using
+	different servers for different upstream domains. Queries which are
+	routed by domain to an upstream server which is not responding will
+	build up and trigger the limit, which breaks DNS service for
+	all other domains which could be handled by other servers. The
+	change is to make the limit per server-group, where a server group
+	is the set of servers configured for a particular domain. In the
+	common case, where only default servers are declared, there is
+	no effective change.
+
+	Improve efficiency of DNSSEC. The sharing point for DNSSEC RR data
+	used to be when it entered the cache, having been validated. After
+	that queries requiring the KEY or DS records would share the cached
+	values. There is a common case in dual-stack hosts that queries for
+	A and AAAA records for the same domain are made simultaneously.
+	If required keys were not in the cache, this would result in two
+	requests being sent upstream for the same key data (and all the
+	subsequent chain-of-trust queries.) Now we combine these requests
+	and elide the duplicates, resulting in fewer queries upstream
+	and better performance. To keep a better handle on what's
+	going on, the "extra" logging mode has been modified to associate
+	queries and answers  for DNSSEC queries in the same way as ordinary
+	queries. The requesting address and port have been removed from
+	DNSSEC logging lines, since this is no longer strictly defined.
+
+	Connection track mark based DNS query filtering. Thanks to
+	Etan Kissling for implementing this It extends query filtering
+	support beyond what is currently possible
+	with the `--ipset` configuration option, by adding support for:
+	1) Specifying allowlists on a per-client basis, based on their
+	   associated Linux connection track mark.
+	2) Dynamic configuration of allowlists via Ubus.
+	3) Reporting when a DNS query resolves or is rejected via Ubus.
+	4) DNS name patterns containing wildcards.
+	Disallowed queries are not forwarded; they are rejected
+	with a REFUSED error code.
+
+	Allow smaller than 64 prefix lengths in synth-domain, with caveats.
+	--synth-domain=1234:4567::/56,example.com is now valid.
+
+	Make domains generated by --synth-domain appear in replies
+	when in authoritative mode.
+
+	Ensure CAP_NET_ADMIN capability is available when
+	conntrack is configured. Thanks to Yick Xie for spotting
+	the lack of this.
+
+	When --dhcp-hostsfile --dhcp-optsfile and --addn-hosts are
+	given a directory as argument, define the order in which
+	files within that directory are read (alphabetical order
+	of filename). Thanks to Ed Wildgoose for the initial patch
+	and motivation for this.
+
+	Allow adding IP address to nftables set in addition to
+	ipset.
+
+	
+version 2.85
+        Fix problem with DNS retries in 2.83/2.84.
+        The new logic in 2.83/2.84 which merges distinct requests
+	for the same domain causes problems with clients which do
+	retries as distinct requests (differing IDs and/or source ports.)
+	The retries just get piggy-backed on the first, failed, request.
+        The logic is now changed so that distinct requests for repeated
+        queries still get merged into a single ID/source port, but
+	they now always trigger a re-try upstream.
+        Thanks to Nicholas Mu for his analysis.
+
+	Tweak sort order of tags in get-version. v2.84 sorts
+	before v2.83, but v2.83 sorts before v2.83rc1 and 2.83rc1
+	sorts before v2.83test1. This fixes the problem which lead
+	to 2.84 announcing itself as 2.84rc2.
+
+ 	Avoid treating a --dhcp-host which has an IPv6 address
+	as eligible for use with DHCPv4 on the grounds that it has
+	no address, and vice-versa. Thanks to Viktor Papp for
+	spotting the problem. (This bug was fixed was back in 2.67, and
+	then regressed in 2.81).
+
+	Add --dynamic-host option: A and AAAA records which take their
+	network part from the network of a local interface. Useful
+	for routers with dynamically prefixes. Thanks
+	to Fred F for the suggestion.
+
+	Teach --bogus-nxdomain and --ignore-address to take an IPv4 subnet.
+
+	Use random source ports where possible if source
+	addresses/interfaces in use.
+	CVE-2021-3448 applies. Thanks to Petr Menšík for spotting this.
+	It's possible to specify the source address or interface to be
+	used when contacting upstream name servers: server=8.8.8.8@1.2.3.4
+	or server=8.8.8.8@1.2.3.4#66 or server=8.8.8.8@eth0, and all of
+	these have, until now, used a single socket, bound to a fixed
+	port. This was originally done to allow an error (non-existent
+	interface, or non-local address) to be detected at start-up. This
+	means that any upstream servers specified in such a way don't use
+	random source ports, and are more susceptible to cache-poisoning
+	attacks.
+	We now use random ports where possible, even when the
+	source is specified, so server=8.8.8.8@1.2.3.4 or
+	server=8.8.8.8@eth0 will use random source
+	ports. server=8.8.8.8@1.2.3.4#66 or any use of --query-port will
+	use the explicitly configured port, and should only be done with
+	understanding of the security implications.
+	Note that this change changes non-existing interface, or non-local
+	source address errors from fatal to run-time. The error will be
+	logged and communication with the server not possible.
+
+	Change the method of allocation of random source ports for DNS.
+	Previously, without min-port or max-port configured, dnsmasq would
+	default to the compiled in defaults for those, which are 1024 and
+	65535. Now, when neither are configured, it defaults instead to
+	the kernel's ephemeral port range, which is typically
+	32768 to 60999 on Linux systems. This change eliminates the
+	possibility that dnsmasq may be using a registered port > 1024
+	when a long-running daemon starts up and wishes to claim it.
+	This change does likely slightly reduce the number of random ports
+	and therefore the protection from reply spoofing. The older
+	behaviour can be restored using the min-port and max-port config
+	switches should that be a concern.
+
+	Scale the size of the DNS random-port pool based on the
+	value of the --dns-forward-max configuration.
+
+	Tweak TFTP code to check sender of all received packets, as
+	specified in RFC 1350 para 4.
+
+	Support some wildcard matching of input tags to --tag-if.
+	Thanks to Geoff Back for the idea and the patch.
+
+	
+version 2.84
+	Fix a problem, introduced in 2.83, which could see DNS replies
+	being sent via the wrong socket. On machines running both
+	IPv4 and IPv6 this could result in sporadic messages of
+	the form "failed to send packet: Network is unreachable" and
+	the lost of the query. Since the error is sporadic and of
+	low probability, the client retry would normally succeed.
+
+	Change HAVE_NETTLEHASH compile-time to HAVE_CRYPTOHASH.
+
+
+version 2.83
+	Use the values of --min-port and --max-port in outgoing
+	TCP connections to upstream DNS servers.
+
+	Fix a remote buffer overflow problem in the DNSSEC code. Any
+	dnsmasq with DNSSEC compiled in and enabled is vulnerable to this,
+	referenced by CVE-2020-25681, CVE-2020-25682, CVE-2020-25683
+	CVE-2020-25687.
+
+	Be sure to only accept UDP DNS query replies at the address
+	from which the query was originated. This keeps as much entropy
+	in the {query-ID, random-port} tuple as possible, to help defeat
+	cache poisoning attacks. Refer: CVE-2020-25684.
+
+	Use the SHA-256 hash function to verify that DNS answers
+	received are for the questions originally asked. This replaces
+	the slightly insecure SHA-1 (when compiled with DNSSEC) or
+	the very insecure CRC32 (otherwise). Refer: CVE-2020-25685.
+
+	Handle multiple identical near simultaneous DNS queries better.
+	Previously, such queries would all be forwarded
+	independently. This is, in theory, inefficient but in practise
+	not a problem, _except_ that is means that an answer for any
+	of the forwarded queries will be accepted and cached.
+	An attacker can send a query multiple times, and for each repeat,
+	another {port, ID} becomes capable of accepting the answer he is
+	sending in the blind, to random IDs and ports. The chance of a
+	successful attack is therefore multiplied by the number of repeats
+	of the query. The new behaviour detects repeated queries and
+	merely stores the clients sending repeats so that when the
+	first query completes, the answer can be sent to all the
+	clients who asked. Refer: CVE-2020-25686.
+	
+
+version 2.82
+	Improve behaviour in the face of network interfaces which come
+	and go and change index. Thanks to Petr Mensik for the patch.
+
+	Convert hard startup failure on NETLINK_NO_ENOBUFS under qemu-user
+	to a warning.
+
+	Allow IPv6 addresses ofthe form [::ffff:1.2.3.4] in --dhcp-option.
+
+	Fix crash under heavy TCP connection load introduced in 2.81.
+	Thanks to Frank for good work chasing this down.
+
+	Change default lease time for DHCPv6 to one day.
+
+	Alter calculation of preferred and valid times in router
+	advertisements, so that these do not have a floor applied
+	of the lease time in the dhcp-range if this is not explicitly
+	specified and is merely the default.
+	Thanks to Martin-Éric Racine for suggestions on this.
+
+	
+version 2.81
+	Improve cache behaviour for TCP connections. For ease of
+	implementation, dnsmasq has always forked a new process to handle
+	each incoming TCP connection. A side-effect of this is that
+	any DNS queries answered from TCP connections are not cached:
+	when TCP connections were rare, this was not a problem.
+	With the coming of DNSSEC, it is now the case that some
+	DNSSEC queries have answers which spill to TCP, and if,
+	for instance, this applies to the keys for the root, then
+	those never get cached, and performance is very bad.
+	This fix passes cache entries back from the TCP child process to
+	the main server process, and fixes the problem.
+
+	Remove the NO_FORK compile-time option, and support for uclinux.
+	In an era where everything has an MMU, this looks like
+	an anachronism, and it adds to (Ok, multiplies!) the
+	combinatorial explosion of compile-time options. Thanks to
+	Kevin Darbyshire-Bryant for the patch.
+
+	Fix line-counting when reading /etc/hosts and friends; for
+	correct error messages. Thanks to Christian Rosentreter
+	for reporting this.
+
+	Fix bug in DNS non-terminal code, added in 2.80, which could
+	sometimes cause a NODATA rather than an NXDOMAIN reply.
+	Thanks to Norman Rasmussen, Sven Mueller and Maciej Żenczykowski
+	for spotting and diagnosing the bug and providing patches.
+
+	Support TCP-fastopen (RFC-7413) on both incoming and
+	outgoing TCP connections, if supported and enabled in the OS.
+
+	Improve kernel-capability manipulation code under Linux. Dnsmasq
+	now fails early if a required capability is not available, and
+	tries not to request capabilities not required by its
+	configuration.
+
+	Add --shared-network config. This enables allocation of addresses
+	by the DHCP server in subnets where the server (or relay) does not
+	have an interface on the network in that subnet. Many thanks to
+	kamp.de for sponsoring this feature.
+	
+	Fix broken contrib/lease_tools/dhcp_lease_time.c. A packet
+	validation check got borked in commit 2b38e382 and release 2.80.
+	Thanks to Tomasz Szajner for spotting this.
+
+	Fix compilation against nettle version 3.5 and later.
+
+	Fix spurious DNSSEC validation failures when the auth section
+	of a reply contains unsigned RRs from a signed zone, 
+	with the exception that NSEC and NSEC3 RRs must always be signed.
+        Thanks to Tore Anderson for spotting and diagnosing the bug.
+
+	Add --dhcp-ignore-clid. This disables reading of DHCP client
+	identifier option (option 61), so clients are only identified by
+	MAC addresses.
+
+	Fix a bug which stopped --dhcp-name-match from working when a hostname
+	is supplied in --dhcp-host. Thanks to James Feeney for spotting this.
+
+	Fix bug which caused very rarely caused zero-length DHCPv6 packets.
+	Thanks to Dereck Higgins for spotting this.
+
+	Add --tftp-single-port option.
+
+	Enhance --conf-dir to load files in a deterministic order. Thanks to
+	Evgenii Seliavka for the suggestion and initial patch.
+
+	In the router advert code, handle case where we have two
+	different interfaces on the same IPv6 net, and we are doing
+	RA/DHCP service on only one of them. Thanks to NIIBE Yutaka
+	for spotting this case and making the initial patch.
+
+	Support prefixed ranges of ipv6 addresses in dhcp-host.
+	This eases problems chain-netbooting, where each link in the
+	chain requests an address using a different UID. With a single
+	address, only one gets the "static" address, but with this
+	fix, enough addresses can be reserved for all the stages of the
+	boot. Many thanks to Harald Jensås for his work on this idea and
+	earlier patches.

-Summary: A lightweight caching nameserver
-
-%description
-Dnsmasq is lightweight, easy to configure DNS forwarder and DHCP server. It 
-is designed to provide DNS and, optionally, DHCP, to a small network. It can
-serve the names of local machines which are not in the global DNS. The DHCP 
-server integrates with the DNS server and allows machines with DHCP-allocated
-addresses to appear in the DNS with names configured either in each host or 
-in a central configuration file. Dnsmasq supports static and dynamic DHCP 
-leases and BOOTP for network booting of diskless machines.

+HOWTO
+=====
+dnsmasq comes with the possibility to run multiple systemd service instances on the same machine.
+There is the main service which is enabled by default via `systemctl enable dnsmasq.service` and uses the configuration from `/etc/default/dnsmasq`.
+
+Additional service instances can be enabled via `systemctl enable dnsmasq@<instance name>.service` that use the configuration from `/etc/default/dnsmasq.<instance name>`.
+It is recommended to use a separate configuration file and directory for each instance.
+Additionally make sure that all instances use either different ports and/or ip addresses to avoid binding collisions.
+
+Example setup for an instance called "alt"
+#1 File `/etc/dnsmasq.alt.conf` copied from `/etc/dnsmasq.conf`
+#2 Directory `/etc/dnsmasq.alt.d`
+#3 File `/etc/default/dnsmasq.alt` copied from `/etc/default/dnsmasq` with following adaptions:
+   * The options DNSMASQ_OPTS and CONFIG_DIR point to the correct configuration file and directory.
+     DNSMASQ_OPTS="... --conf-file=/etc/dnsmasq.alt.conf ..."
+     CONFIG_DIR=/etc/dnsmasq.alt.d,.dpkg-dist,.dpkg-old,.dpkg-new
+   * The option DNSMASQ_EXCEPT must contain "lo" to avoid that an instance becomes the machine's DNS resolver.
+     DNSMASQ_EXCEPT="lo"
+  * If the additional instance should bind to all IP addresses of a specific interface, e.g. "dnsalt01", then the following addition could be used:
+    DNSMASQ_OPTS="... --bind-dynamic --interface=dnsalt01 ..."
+    Additionally the main instance must be stopped from binding to interfaces that are used by other instances:
+    DNSMASQ_OPTS="... --bind-dynamic --except-interface=dnsalt* ..."
+  * If the additional instance should not use the machine's DNS resolver, normally that's the dnsmasq main instance, as upstream server, then the following addition could be used:
+    IGNORE_RESOLVCONF=yes
+#4 Enable additional instance via `systemctl enable dnsmasq@alt.service`
+#5 Start additional instance without reboot via `systemctl start dnsmasq@alt.service`
+
+
+
+TODO
+====
+#1 - Found shortcoming on 2019-03-10
+Only the option DNSMASQ_EXCEPT="lo" avoids that an DNS instance will be set as the machine's DNS resolver.
+This may interfere with the wish to run an additional instance on a different port on the localhost addresses.
+My suggestion in the initial Debian report [1] was to specify an explicit variable for this.
+
+[1] https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=914305#5
+
+
+#2 - Preferred configuration way
+Should the variables DNSMASQ_INTERFACE and DNSMASQ_EXCEPT be used instead of --interface and --except-interface?  (while "lo" still has to be in DNSMASQ_EXCEPT as of now)
