not to hijack the thread here but this is not just a valid point, but a very
inteligent point. Picking a specific stable distro and package list allows
a person to maintain all identical setups, document the system and the
configuration, and redeploy identical systems. I run ubuntu 7.04 with
backuppc 3.0 and have not upgraded to 3.1 on production machines. I will
wait until 8.10 is out before deploying any 8.04 servers so that bugs can be
squashed and packages can stabilize.
