A friend (hi Dave) and I grabbed Fedora Core 5 the day after it was available and built a VM out of it. I think that this is the first version from Red Hat (FC RHEL, and the older distros) that didn't have an error during install. Maybe things are improving? Finally?
Then again, I could be doing something wrong (you ever have that feeling?). An install of the latest OpenBSD also went off without a hitch.
