Re: Crash

[Andreas Kahari <andreas@tdb.uu.se>]

The 'halt' command in Debian behaves as if I typed 'shutdown -h now',
i.e. it sends TERM and KILL to all processes and stops all daemons, and
finally prints "System halted" (if I press the big red button, which I
won't do, this naturally won't happen). I still get "crash"... 

Here's some output from the 'last' command on my system:
andreas  tty1                          Mon Oct 26 18:53   still logged in
reboot   system boot                   Mon Oct 26 18:53  
root     tty1                          Sun Oct 25 14:20 - 14:21  (00:00)
reboot   system boot                   Sun Oct 25 14:20  
root     tty1                          Sun Oct 25 14:14 - crash  (00:03)
reboot   system boot                   Sun Oct 25 14:14  
andreas  tty2                          Sun Oct 25 13:59 - crash  (00:12)
andreas  tty1                          Sun Oct 25 14:53 - crash  (00:-41)
reboot   system boot                   Sun Oct 25 14:53  
andreas  tty1                          Fri Oct 23 20:54 - crash  (01:08)

I notice now that 'reboot' won't cause a "crash", but 'halt' *and*
'shutdown -h now' will.

Also, CTRL-ALT-DEL (in inittab: "ca:12345:ctrlaltdel:/sbin/shutdown -t1
-h now") will cause "crash" (I changed this entry in inittab from "-r"
to "-h", which is what I want CTRL-ALT-DEL to do). 

But, as I said, nothing appears to be wrong. Everything works fine,
except for the word "crash"...
