This is on a host with 2.4.25+grsec+vs1.3.8.
Multiple problems with reboot from inside a vserver running debian sarge (testing):
1.- Not a problem of the utils but of my setup:
I have a setup where the vserver tools are inside a chroot, not on the plain host.
This is because I want to keep woody on the host, but the alpha tools only compile on
sarge/sid. So I have sarge in a chroot, installed util-vserver-0.29.207 there, and for
vserver maintenance I first enter this chroot. Since the reboot request is made by the
kernel to the plain host, I had to write a proxy vshelper script:
#!/bin/sh
# cj Mon, 12 Apr 2004 04:51:16 +0200
# proxy kernel requests into the chroot (sigh)
cmd="chroot /chroot-sarge /opt/vserver/lib/util-vserver/vshelper $2 $1"
{
echo "`date -R` cmd='$cmd'"
$cmd
res="$?"
echo "`date -R` returned from chroot with: res = $res"
} >> /tmp/root/vshelper.log 2>&1
Additionally, I had to comment out this part in the original vshelper script to be
able to see what's happening (I should probably have defined logfile settings--but
then again I just wanted the output directed to my log together with my own output
from the proxy script):
#if ! tty -s; then
# findObject -e _VS_LOGFILE "$CONFDIR"/.defaults/apps/vshelper/logfile /dev/null
# findObject -e _VS_ERRFILE "$CONFDIR"/.defaults/apps/vshelper/logfile /dev/null
#
# exec >>$_VS_LOGFILE
# exec 2>>$_VS_ERRFILE
#fi
2.- As you can see from the above script, I had to change the order of the arguments
to make it work. Before that, vshelper complained about
No responsible vserver found for xid 'restart2' (restart2); aborting...
3.- Only "reboot -f" does seem to work in debian, "shutdown -f now", "halt" etc are
just complaining about missint /dev/initctl and stop. Why is there no initctl if
there is an init process running? (The rather strange thing about this is, that reboot
-f usually does circumvent the normal shutdown process, but in this vserver case, it
will still shut down the vserver cleanly (wrong "semantics").)
4.- Rather cosmetic, but it might interest you: the vshelper is triggered twice for
each argument (four times in total) for one "reboot -f":
