Well, I’m pretty pleased with CentOS so far.
I just completed a minor version upgrade (5.5 to 5.6) via yum and it went very smoothly. This involved 3 virtual guest and one host (the guests run inside the host).
I had one small glitch with the RPM database on middle-earth. Some dependencies were screwed up, but that was corrected by running
yum clean all.
In order to speed things up, I’m going to be mirroring the most current CentOS package repository on middle-earth … that way I can get the updates done much quicker (installs too).
