Thanks to the work of Michael Goetze, who worked on CentOS support in FAI, we are now able to deploy a standard install of CentOS 5 (5.5) in round about 143 seconds.

The default chroot tarball was created using the "rinse" tool by Steve Kemp.
That reminds me, that I still have some patches for this tool pending and as well some more fedora distro support files to push to Steve.

The important part about this is, that CentOS is not so different from RHEL, so if you have a working yum repository for RHEL, then you are able to install RHEL as well. But having a
