[CentOS] Chroot tool

Hi,

Currently I'm working on building chroot environment for a several 
users. The needs of those users are different, so the binaries and their 
libraries are differents too. The building process tends to be so tedious.

I'm using a odd script to automatize the copy of needed libraries, but 
it not works very fine.

¿Is there some tool to automatize the chroot jails creation/management?
¿Do you use some kind of shell-script?
