So I've been thinking about repartitioning my drive to the traditional 
unix format, eg. having one partition for /home, one for /usr, one for 
/boot... And I'd like it if I didn't have to reinstall Ubuntu again. 
That may be too much to ask, but... What are the advantages of doing 
that, if anyone knows? I could (apparently) easily use the Knoppix cd to 
repartition my drive and move everything over, edit the fstab and the 
grub config and theoretically be good to go, right?
