RE: Moving partitions around...
Absolute safest thing to do is backup the partition (or maybe only your files).
using dpkg --get-selections and a little scripting, you can get a list of every
package on your system. pass that data into dpkg --set-selections and you get
your old system back. So all you really need to save is home directories,
/etc, and maybe /usr/local.
Anything else is just not safe enough in my book. As for the physical move,
/etc/fstab will need to be touched and lilo re-ran. Notthing else should
depend on the name of the partition I can think of.
