[mythtv-users] Relocating a system?

Whats the fastest way to migrate a system from one partition to another?

My MythTV-box started out as a FC2-box, because I felt that Jarods guide
was the best Myth-Howto at the time. I recently migrated this to Debian,
since all my other boxes are Debian.

When I originally installed the system, I left 3GB for a "future upgrade
to Debian project", but now I am finding that partition a bit crowded.

So, I would like to move my system from hda5 -> hda2.

So, I figure I could do a 'cp -a' and edit fstab. But what about
booting? Would it really be so easy as to just edit grub.conf to the new

So from, 

root            (hd0,4) 


root            (hd0,1)
