Fresh install of RedHat 2.1. Upon attempting to update the local rpm database, it prints out a message that it can't find /mnt/sysimage/var/lib/rpm/packages.rpm (probably because it didn't exist in RH2.1!). The install then fails out, claiming there's probably not enough disk space free.
We're not going to support upgrading from 2.1. You'll need 3.0.3 or greater.
