The UTMP db tracks currently logged in users and WTMP is an audit trail
of all user logins and logouts, as well as runlevel changes and reboot.

The new logit() function takes care to print to stderr if syslogd has
not yet started. The _d(), _e(), and _pe() macros have an additional
requirement: to always print on stderr.
After the boot we also want to see what happned during, so this patch
simply adds syslog() support to _d(), _e(), and _pe().

This patch removes internal logging macros and adds support for logging

This patch removes accounting for all processes to instead implement the

This patch adds initial support for handling MD RAID arrays. Adding
a pass at the very end of the shutdown sequence to signal any external
RAID controller to clear its state before we proceed to halt/reboot.

This patch adds support for a more fine grained approach to what
filesystems are unmounted at shutdown/reboot. This so we later
can add support for `mdadm --wait-clean --scan`, which relies on
/proc, /sys, and /dev being there before we call reboot().

Also, this code will be refactored soon to be a part of the finit

This patch is a complete rewrite of the Finit reboot command. Not only
does it bring it up to speed with the new signal model, but it also adds
new features like poweroff, halt, and suspend -- including a forced mode
that goes for reboot(2) immediately.

This patch fixes the ordering of UTMP events. The first event that is
expected in /var/run/utmp is reboot, next is the runlevel change to
the configured runlevel, e.g. from S --> 2.
Let the bootmisc plugin handle this, it knows when /var/run/utmp has
been created and is writable. It is not the eact boot time, but close
enough for most usees.

This patch adds support for initializing /var/run/utmp with the initial
reboot as well as a shutdown record in the UTMP db.
Also, the run level change now properly records ~ and ~~ as line and id,
respectively, and the kernel release and time of each UTMP record is now
set properly.

This patch adopts the BusyBox init signals for handling halt, reboot,

That's maybe a bit unfair. This patch implements a brief version of
what is really needed to safely unmount all file systems on a modern

worse! Just have a look at the ancient scrolls hidden in your /etc!)
Here is where we use the new plugin_exit() and api_exit() API's from an
earlier patch. Making sure to exit and close any kernel descriptors.
Then follows a bizarre spell cast on leaking descriptors, rebooting in

stuff to prevent mount/umount from returning 32 ...

The TTY handling in Finit has always been a bit of a patch work. This
