how to move /tmp to different drive?
using KDE, Debian testing amd64.

Create a partition on the new disk for /tmp, create a filesystem on it, add an entry to your fstab (or, if you use systemd, a .mount file) for /tmp.
Reboot, or manually mount /tmp to its new location. You may want to boot into single user mode, to clear out any cruft in the old /tmp location, just mounting the new one over the old stuff will only hide that cruft, but not delete it.

thanks Tobi.
but I'd like to move it to a directory on a different drive, not partition.
I've tried 'ln -s' but that didn't work.

/tmp can be needed during the boot sequence before other filesystems have been mounted. Making /tmp a symlink would break that rather badly. You could use "mount --bind /some/directory /tmp", or in /etc/fstab:

Code:

/some/directory  /tmp  none  bind   0 0

The mount point directory would still be there and available for early users

This should work exactly the same way as any new partition. You are pointing your system at a partition. As long as it exists your system doesn't care what drive it is on, only that you point it in the correct direction.
