Actually I want to use those two partitions for something else so
if I can get /var and /tmp to point back to the partition
designated as / I will reformat them and mount them elsewhere.
I tried commenting out the fstab line for /tmp last night and then
rebooting and got a broken system but was able to boot into a command line
mode and replace the edited fstab with its renamed .bak
Guess I need to download a current Knoppix iso and work off it.
Incidently Ubuntu now sets fstab up with these nasyt assignment lines that
look like this:
#Entry for /dev/sda8 :
UUID=be9d8546-17ea-4f34-901c-ccdb66b30195 /tmp ext3 relatime
If you do not have the correct funny number after UUID then the partition
does not mount.
I have two sxt2 partitions on my external USB back up drive that I do not
have permission to mount on boot now since an Ubuntu upgrade put the funny
numbers in my fstab. The FAT partitions on the same drive still mount.
Part of the reclaiming space from /tmp and /var was to get some space I
could copy stuff to from the external drive prior to fiddling around with
it. I think I can mount the ext2's by hand but I was trying to solve the
/var and /tmp reassign first.
Any thoughts on this matter?
