I'm running out of space on my /usr partition. What I would like to do is temporarily move /usr to the partition where / lives (I made / a bit too big, and /usr too little). Then resize the /usr partition.Then mount /usr back to the /usr partition. i.e.

Currently: hda1 / hda6 /usr

Then:

hda1 /

(cfdisk shenanigans to increase size of hda6)

Then back to: hda1 / hda6 /usr

However, as /usr contains most my programs, I am unsure as to how to do it.

My plan is to boot into a rescue disk (or would single user mode and a normal boot work? if I unmount /usr), change /etc/fstab (to not mount the /usr partition), make a dir called /usr on the root partition, copy the contents of the /usr partition to the /usr on the root partition. Reboot to check, then back into the rescue disk, cfdisk to enlargen the partition formerly known as /usr, mke2fs to create the file system,copy /usr on the root partition to the new one, change the /etc/fstab to mount the new /usr, and reboot.

I'm a little concerned in case permissions change... but does that sound right? Am I missing anything?

TIA Ricardo
