You bet! I would create an entirely new tmp dir (say /temp or /tmp2), then
set the TMPDIR environment variable in /etc/profile. A great many programs
use TMPDIR (vi, cc, sort, etc.). If a program uses tmpnam(3S) or tempnam(3S),
which ALL programs should, then you can direct tmp use anywhere you want.
You can get a lot of speed-up on compiles if you put tmp on a disk not
involved in the compile.
