saves your day if you get unexplainable errors from rpm install because /vservers/test has bad permissions:

# la -d /vservers/test/
drwx------  23 root root 4096 Jun 16 02:01 /vservers/test/

# vrpm test -- -Uhv masqmail-0.2.20-5.amd64.rpm

real fix would be 'chmod 755 /vservers/test' if you just knew that is the problem!
