It is in /vserver/vserver1/bin/rpm allright - I simply don't get it.
If I do a:

vserver vserver1 exec rpm -q apache

- it works fine. Same if I add "suexec root" - no problem, it just
executes. Weird.

OK - now it works.

Yay! THAT would be pretty cool! :-) Now if someone would please buy
me that 8-way Xeon with 32 gigs of RAM and 4 TB of RAID5.... *GRIN*

Seriously, I think that it is pretty amazing what can be done with a
slightly modified Linux kernel, a collection of small utilities and
som pretty standard hardware - well done.
