Subject: Util-vserver build from template modifies uid/gid

I have a problem when creating vservers from template using the 
util-vserver tools, perhaps someone else has already fixed this:

The template tar has correct uid/gid:

tar --numeric-owner -tjvf ../vs-ubuntu710-minimal-2007-11-27.tar.bz2 | 
grep var/lock/logcheck
drwxr-xr-x 103/109           0 2007-10-15 17:28 ./var/lock/logcheck/

After importing the uid/gid are wrong:
vserver-build -n - --hostname vs-test -m template -n vs-test -- -t 
vs-ubuntu710-minimal-2007-11-27.tar.bz2
ls -aln vs-test/var/lock/logcheck/
drwxr-xr-x 2 102 109  1 2007-10-15 17:28 .
drwxrwxrwt 3   0   0 16 2007-10-15 17:29 ..

On vserver utils .213 this workaround helped, but now it doesn't:

Change: /usr/lib/util-vserver/util-vserver-vars
   _TAR="/bin/tar --numeric-owner"

Now after machine upgrade (ubuntu 710, util-vserver 30.214, kernel 
2.6.22.12-vs2.2.0.5) this setting is ignored (ps during extract, uses 
tar -x):

root@localhost:/data/vservers# ps auxw | grep tar
root     18367  0.1  0.0    108    28 pts/2    S+   14:15   0:00 
/usr/sbin/vnamespace --new -- /usr/lib/util-vserver/vserver-build -n - 
--hostname vs-test -m template -n vs-test -- -t 
vs-ubuntu710-minimal-2007-11-27.tar.bz2
root     18369  0.2  0.0   4276  1796 pts/2    S+   14:15   0:00 
/bin/bash /usr/lib/util-vserver/vserver-build -n - --hostname vs-test -m 
template -n vs-test -- -t vs-ubuntu710-minimal-2007-11-27.tar.bz2
root     18403  0.4  0.0   2900   596 pts/2    S+   14:15   0:00 
/bin/cat /data/vservers/vs-ubuntu710-minimal-2007-11-27.tar.bz2
root     18405  5.2  0.0   3464  1092 pts/2    S+   14:15   0:00 tar -x

The only possible workaround until now is to create a tar shellscript:
#!/bin/bash

exec /bin/tar --numeric-owner $

and export PATH=.:$PATH before executing the build command


Any idea?
