[NTLUG:Discuss] parted, win dual boot & linux

[Greg Edwards]

I'm a big time believer in KISS.

Rebuild sda2 as ext4 and mount it (maybe /mnt/home2 or /home2).  Move 
some /home/{somename} directories to /mnt/home2/{somename} and symlink 
to them from /home.

Next time you upgrade hardware or rebuild the box move the 
/mnt/home2/{somename} directories back to /home.

YMMV
