Unmount /tmp.

(You don't need single-user mode as long as there aren't any other users
on the system, but you might want to get out of X as you mention.)

Then remount /tmp on your bigger partition (this assumes your bigger
partition is empty). You can even make it a permanent change by changing
/etc/fstab.

If your bigger partition is not empty, just unmount /tmp, then just do
the symlink like you did above, but don't reboot or remount /tmp. The
system should find /tmp just fine.

I don't know k9copy, is there a way to have it use another directory
than /tmp, e.g. by a command-line option or by setting TMPDIR? If not,
you should file a bug report to the k9copy authors, because putting huge
files in /tmp is just plain wrong. These days it makes sense to mount
/tmp on a tmpfs filesystem, and writing DVD images there thwarts this
possibility.

If k9copy reads an environment variable (usually TEMP or TMP) to find
the temporary directory, you could try setting that to somewhere that
has more space (e.g., ~/tmp). Its documentation might say more about which
environment variables it respects. If it's a GUI program, you could also
check its interactive configuration and see whether there's a setting
controlling where the temporary files go.

Thanks. I found the config option to change the directory used. No more
problems.

Also thanks to everyone else who answered. I got a lot of useful tips from
your replies. Its great to have so many smart and well versed folks on this
list.

Is it possible to increase the space available in /tmp without doing the
backup/repartition/reinstall/restore dance?

I'm trying to backup a dvd using k9copy. It wants to have about 8 gig free in
the /tmp partition, but when I set the system up, I gave /tmp much less than
that. k9copy wants to write to /tmp/kde-mark/k9copy* so I tried creating a
link from /tmp/kde-mark to a partition with lots of space (while in single
user mode since messing with /tmp when "X" is active can be dicey). I made
sure the permissions were correct, but when I restarted in normal mode, the
system created and used a sub-directory under /tmp like
this: /tmp/kde-mark6C5838b thereby circumventing my efforts. Do I have to
backup, repartition and restore or is there a better way?

Thanks,

Mark
