F12 wants about 300Meg for /boot. I used 50 iirc on F6 through F8 and 75 
Meg for F10. On this desktop (F12) I dropped /boot. It was easier all 
round.

Regarding settings, an easy route is to rsync a copy of /root, /home 
and /etc onto your storage drive/partition and then copy things back as 
needed. There are. realistically, only about a dozen files which you 
need to copy back or update, but it's nice to just be able to copy them 
especially if they are 'tricky': alsa/sound, fstab for nfs mounts, 
profile for path changes, hosts, resolv.conf, iptables for any special 
port forwarding setups (external access to mythweb)....

BTW, /home should matter to you. If you have used the canonical setup, 
you have a 'mythtv' user, and lircrc lives in /home/mythtv. Plus your 
mysql setup will give problems without a config.xml file....etc.

Exactly: Time to plan now!
