Due to an old design decision runlevel S was encoded internally as '0',
meaning it was the same as halt/poweroff. If you want to run scripts at
system shutdown this was less then ideal since it meant your scripts
also ran at bootstrap.
This change is quite invasive. It introduces INIT_LEVEL (10) as the
value for runlevel S, meaning all code that parses and/or evaluates
anything for runlevel 0/S was affected and had to be reworked.

The accepted standard in Unix is to report successful executions with
exitcode 0. Therefore, map a "initctl cond get" of a condition to the
following exitcodes:
- On: 0
- Off: 1
- Flux: 255
Fixes: c3c662fe64 ("initctl: ensure 'cond get' support flux state")

The 'initctl cond' commands were initiallý added to only manage usr
conditions. Recently the 'cond get' command was expanded to allow
reading general conditions as well.
However, since general conditions support three states the command
returned 'on' for conditions that were in flux. This patch fixes
that oversight.

Principle of least surprise. When no even the maintainer remembers

This change adds support for a new command line option finit.config=PATH
which can be used to tell Finit to start with /etc/factory.conf instead
of /etc/finit.conf.
For the complete experience a new top-level configuration file directive
`rcsd PATH` has aslo been added. It in turn can be used by factory.conf
as follows to override /etc/finit.d:
rcsd /etc/factory.d

This change adds support for JSON output to `initctl status` using a
`-j` or `--json` command line option.
Example:
root@anarchy:~# initctl status -j mdevd
{
"identity": "mdevd",
"description": "MDEVD Extended Hotplug Daemon",
"status": "crashed",
"exit": { "code": 100 },
"origin": "built-in",
"command": "/bin/mdevd -C -O 4",
"restarts": 10,
"pidfile": "/run/mdevd.pid",
"pid": 0,
"user": "root",
"group": "root",
"uptime": 0,
"runlevels": [ "S", 1, 2, 3, 4, 5, 7, 8, 9 ]
}
The excellent tool `jq` can be used to extract certain parts of the
output for further scripting. E.g. `initctl status -j foo | jq .exit`

This is a fix to a regression introduced in e51587c. The idea is to
have 'initctl status foo' show all instances of foo, provided there are
more than one. E.g.
root@anarchy:~# initctl -t status foo
0 foo:1 stopped [--234-----] hej knekt
0 foo:2 stopped [--234-----] hej snigel
0 foo:3 stopped [--234-----] hej kalas
And not foobar:
0 foo:1 stopped [--234-----] hej knekt
0 foo:2 stopped [--234-----] hej snigel
0 foo:3 stopped [--234-----] hej kalas
0 foobar stopped [--234-----] hej foobar
If you type an exact match you can drill down like so:
root@anarchy:~# initctl status foo:1
Status : stopped (code=exited, status=0/SUCCESS, manual=yes)
Identity : foo:1
Description : hej knekt
...

Prior to this change only service stanzas respected the manual:yes
option, now it (should) work on any svc_t type. Not tested on ttys.
The initctl tool has been given an extra manual=yes output for these
types of run/task/service entries, shown only when the manual option
is set.
Example:
root@anarchy:~# initctl status foo.sh
Status : stopped (code=exited, status=0/SUCCESS, manual=yes)
Identity : foo.sh ~~~~~~~~~~~~
Description : Hej foo
Origin : /etc/finit.d/enabled/foo.conf
Environment :
Condition(s):
Command : /root/foo.sh
PID file : none
PID : 0
User : root
Group : root
Uptime : N/A
Starts : 1
Restarts : 0 (0/10)
Runlevels : [--2345----]
Notice also the new `Starts : 1` which is a counter for the number of
starts in the current runlevel. On runlevel change it is reset to 0.

Allow filtering of conditions in raw dump, i.e., the possibility to show
only conditions of a certain type. The TYPE argument is not validated
in any way, so any prefix match is allowed, e.g.
initctl cond dump service/s
Shows all conditions for services starting with 's'.

Move the stop+start from initctl to the state machine by allowing
stopped tasks to restart once it has been collected. This should
prevent finit from blocking, allowing it to handle other requests
while waiting for the service's PID to be collected.
Effectively, this will allow a service to call initctl to restart
itself, as reported in issue #280.

This change diversifies the exit codes used by initctl on fatal errors.
Previously only Std C codes 0 and 1 were used, with the initctl specific
255 for some cases.
Both the LSB init script codes and BSD sysexits.h codes are used. See
util.c exitcodes[] for the full list. The idea is to complement the
change in 9a76f08, issue #266, so that initctl can be used silently for
scripting purposes.

This patch introduces ERR(), ERRX(), WARN(), and WARNX() as replacements
to their lower case counterparts. These log macros respect the 'quiet'
flag to initctl, leaving only the return code as indicator to user.

No need for the verbose output on error, simply state the cause of the
problem. The user can issue `initctl -h` to check the syntax of the

What a ride, apparently we support restarting run/tasks in the same
runlevel they have already started once in. Still unsure if adding
support for reloading a particular Finit .conf file for a service
should be in the context of this command (it isn't now). Maybe it
is better left as a future expansion when we switch to the new .conf
format?

In some (error) cases the PID known to Finit may no longer exist, or may
not have been added to a cgroup (yet). Handle this case by skipping the
output of cgroup info in such conditions.
