Re: [PLUG] Moving /usr to a new partition properly

[Barry Spindler <archmage@i-o-r.net>]

After formatting and mounting the new partition do 

	cp -a /usr/* /mnt/new_part

This will copy all files (and directories) under /usr, preserving 
permissions, ownership, and symlinks. Then umount the new partition.
Change fstab to point the new partition to /usr, move /usr out of the way,
and mount the new partition to /usr. That should be it.. you shouldn't have
reboot for this :)

There was a young fellow named Morgan
Who possessed an unusual organ:
	The end of his dong,
	Which was nine inches long,
Was tipped with the head of a gorgon.
