right now(old disk) im dual-booting LM and Debian. i'm using GRUB.
After i transferred debian in the new HD, should i `install-mbr`?
or reinstalling a bootloader would cause debian to _automatically_
install the MBR for me?

will this be ok?
/ --> EXT3
home --> EXT3
usr --> XFS
var --> XFS
or
/ --> XFS
home --> EXT3
usr --> XFS
var --> EXT3
any thoughts?
