Syntax:
[pre|post|ready]:[0-3600,]/path/to/script
Description:
Before this patch all pre/post/ready scripts used the global kill
delay as timeout. After this patch it is possible to disable the
timeout as well as set a timeout >60, which is max kill delay.

Follow-up to 465bc17, which addressed unintended restart of siblings.
This patch fixes a problem where template instantiated services are not
properly reloaded/restarted when marked as "dirty" with `initctl touch`.

add support for 'nofail' fstab option. if present, finit's fsck invocation ignores errors for this device.
this is useful if you have an fstab entry for a device with UUID= or LABEL= which isn't always present and which you'd like to not
bail on (so you set nofail). in this case finit leaves the presence-or-not decision to fsck, which exits nonzero.
for block devices that are directly listed in fstab this change isn't important, because for such finit looks for the blockdev's existence and skips the fsck if n/a.
Consider the case where container@.conf is an available template. When
creating a container@foo.conf it will share the same base .conf as an
existing container@bar.conf, but we do not expect to restart bar just
because foo is instantiated.
Up until this change, all template siblings were considered "dirty" if a
new one was created or updated. Skipping realpath() for all files that
have a '@' works around the problem.

These plugins signal success and failure directly to the console, the
user should inspect syslog for more information.
This change is a follow-up to 340cae4, where kernel logs of LOG_ERR and
higher are allowed to log directly to the console. Since syslogd has
not been started before these plugins, the log messages would otherwise
leak to the console.

In 42ef3d3c, for v4.4-rc1, support for setting a custom RTC restore date
was introduced. Unfortunately the configure script was wrong and caused
config.h to contain
#define RTC_TIMESTAMP_CUSTOM "$rtc_date"
instead of
#define RTC_TIMESTAMP_CUSTOM "2023-04-10 14:35:42"
Furthermore, the error handling for strptime() was wrong, so the restore
date was always reverted to the default.
This patch fixes both issues and extends the DATE of --with-rtc-date to
also include seconds.

This patch introduces a new configure option --with-rtc-file=FILE. When
enabled the RTC plugin detects missing RTC device and falls back to save
and restore system time from a file instead. When --with-rtc-file is
used without an argument the default file is /var/lib/misc/rtc, but the
feature itself is disabled by default.
The usefulness of this feature may not be obvious at first, but some
systems are equipped with an RTC that resets to a random date at power
on. This can be really bad in the case the date is far in the future,
because an NTP sync would then cause time skips backwards, which shows
up in logs and causes a whole lot of pain in alarm systems.
The solution is to disable the RTC driver or device tree node, and when
Finit starts up, the RTC plugin detects a the device node and instead
restores time from the last save game. Meaning time will always only
move forwards.
NOTE: when Finit is built --with-rtc-file we always save to disk, but
only restore from the "save game" if restoring from RTC fails.
If the system has no RTC we always restore from disk.
As an added bonus, this change also makes sure to periodically
sync also the RTC with the system clock. Useful for systems
that do not run an NTP client.

Some boot loaders, like GRUB, leave background color artifacts from
their boot menu. This patch resets the foreground and background
color attributes, and then clears the screen, without clearing the
scrollback buffer.

This patch changes a behavior that's been default since Finit 4.0,
introduced in 4d05bf9 with 4.0-rc2.
If service B depends on A and A needs to be reloaded, then B may be
affected. If A is declared as NOHUP <!>, then A will be stopped and
restarted, during which time the condition it provides is removed,
and B will also be stopped.
However, and as of this patch, if A is declared supporting HUP, then the
condition A provides will only go into flux, during which time B will be
SIGSTOPed instead of needing to be reloaded.

When dealing with "L+" and "R", the function call 'nftw' should not
follow symbolic links, otherwise, it would also delete the targets
which is wrong.
For instance, if there is already a symbolic link:
```
/path/to/the/link -> /path/to/some/folder
```
if we set the following in a tmpfile conf:
```
L+ /path/to/the/link - - - - /path/to/the/target
```
the result would be /path/to/some/folder also get deleted, which it
should not.
it could be even worse, when the symbolic link already is pointing to:
/path/to/the/target, the whole /path/to/the/target would be deleted on
next system boot.

A Linux system booted with the kernel command line option 'quiet' only
logs error (and above) severity messages to the console. For embedded
systems, which is the primary target for Finit, this is what you want
to see.
Hence, and after careful consideration, this patch changes the default
behavior of Finit to allow kernel logs to the console. A build-time
configure flags, --disable-kernel-logging, has been added to restore
legacy behavior.

Systems that have the following tty setup and multiple consoles listed
in /sys/class/tty/console/active misbehave:
tty [12345789] @console 0 xterm noclear passenv
Only the first listed console is started properly, the remaining ones
were registered using the wrong :ID and no arguments to getty.
This patch fixes the parsing and re-use of the base paramenters for
all consoles listed in the active file.
