fedora9
I started using Fedora9 yesterday. Unfortunately, its not been a very enjoyable experience thus far. The biggest issue is that out of the box, Fedora9 is incapable of mounting any remote (NFS) filesystems during boot. Normally, this just requires adding the entry /etc/fstab, however in Fedora9 it just silently fails. After some research, it turns out that the bug is in the original initscripts package, and is fixed by updating to a 0-day update.
Then there's the mess known as NetworkManager. Starting with Fedora9, NetworkManager is now the default, and seems to have a mind of its own. It brings up eth0 seemingly at random during the boot process, and often after the netfs init script runs, which results in the NFS servers not getting found or connected to. The solution here was to uninstall NetworkManger altogether, replace it with /etc/init.d/network, and move on with my life.
