It really belongs in the "init" program. OK, I'll do that.

By the time the system is halted, all disks are mounted read-only, and it is
no longer possible to write the run level.

I'll look at the other problems.

Package: sysvinit
Version: 2.57b-1

After the system is halted, the three finger salute doesn't reboot it
(instead, init complains about no /var/log/initrunlvl).  To fix: use
the ctrlaltdel program from util-linux (add "ctrlaltdel hard" after
the filesystems are unmounted in /etc/init.d/halt), or add a reboot()
call with correct magic values in the halt program.

BTW, I'm not sure if too much FSSTND is a good idea here - if /var is
a separate filesystem and it is not mounted, it is not possible to change
runlevels.  The traditional file name is /etc/initrunlvl.  Same goes for
the shutdown.pid file, too.

Another problem with sysvinit: sometimes, if I press Ctrl-Alt-Del, it
prints the following messages (from memory, they may differ slightly):

INIT: Switching to runlevel 6
INIT: Sending processes the TERM signal
INIT: Sending processes the KILL signal
INIT: No more processes left in runlevel 6

and then just hangs (but some processes are still running, for example
gpm - I can see that by moving the mouse).  Pressing C-A-D again doesn't
help (results only in two INIT: messages, the first and fourth one),
only the reset button does.  Small suggestion for init (unless it already
does this): no matter what is in the /etc/inittab "ctrlaltdel" line,
always sync() on C-A-D before doing anything else.

While we are at it, yet another (only cosmetic) problem with init:
I suggest to do something like "stty sane" in shutdown scripts -
the shutdown messages are printed without carriage returns...
