Hi --

Recently I've started working with fairly large image files using Krita (it's the only app I've found that will do 16-bit grayscale image. The problem with Krita is that you cannot tell it where to store temp files while you're working, and these files get quite large.

I have two HDDs in this box; the boot disk is 80 mb and the slave is 160. Here's what df -h looks like:

marc@machupo:~$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 259M 172M 73M 71% /
tmpfs 1007M 0 1007M 0% /lib/init/rw
udev 10M 112K 9.9M 2% /dev
tmpfs 1007M 0 1007M 0% /dev/shm
/dev/sda11 9.2G 596M 8.1G 7% /home
/dev/sda9 33G 177M 31G 1% /opt
/dev/sda8 373M 11M 343M 3% /tmp
/dev/sda5 4.6G 2.8G 1.6G 65% /usr
/dev/sda10 19G 186M 18G 2% /usr/local
/dev/sda6 2.8G 315M 2.4G 12% /var
/dev/hdb9 117G 12G 105G 10% /odisk/opt
/dev/hdb7 953M 202M 752M 22% /odisk/home


The slave disk currently is only mounted for the old /home (for stuff that hasn't yet been migrated) and for the /opt partition, which has a lot of stuff I want to keep.

What I would like to do is take part of that old disk (from the /opt partition) and somehow convince this machine that it should use that as /tmp, at least for KDE sessions that I'm running.

I've been poking around all over the place looking for an elegant and permanent way to do this, and haven't come across anything. I'm wondering whether any of you have any ideas.

Thanks for any ideas!
