Hi,

I encountered a strange problem today on a SuSE 9.0 machine (SMP).

After compiling util-vserver as usual and trying to start a vserver, I
got the following error:

[...]
New security context is XXXX
Can't chroot to directory . (Operation not permitted)

Debugging the problem together with Herbert, we found out that, for
some reason, the utilities drop capabilities when they shouldn't.

Herbert suspected this was a compiler problem and suggested I
recompile util-vserver on another machine - and it worked indeed.

The box this problem happened on was SuSE 9.0 as said above, with gcc
3.3.1 (RPM release 3.3.1-29).

I might need to mention this worked fine on another SuSE 9.0 with the
only difference being SMP - so my guess would be this is a problem
when using SuSE's gcc to compile util-vserver on SMP machines.

Just in case someone else should encounter this problem... The fix is
simple: Compile util-vserver somewhere else. ;-)

Cheers
Chris
