[olug] swap problems

[Cesar Delgado]

I'd unmount the swap, or if it's umounted then I'd do nothing.  Then I'd 
make sure the swap was /dev/hda5 and I'd run:
mkswap /dev/hda5

Then I'd go into the fstab, take out the line with the UUID and just add:
/dev/hda5	none	swap	sw	0 0

Then I'd run:
mount -a

And the swap should be mounted and happy.
