"setquota" interrupts virtualmin working

Last night, I try to install virtualmin on CentOS 5 and it had tried to "setquota" for a long time, but it seemed to be never end :D
Oki, then :
- Ctrl - C to terminate the installation
- rename /usr/sbin/setquota setquota.bak, make a new setquota:

# cd /usr/sbin/
# mv setquota setquota.bak
# echo "exit 0;" > setquota
# chmod 755 setquota

Now let run the installer again :D
