Good idea!

Yes, I've symlinked /tmp to ramdisk on a few embedded projects

Yup, poor system design! When I manually partitioned some time back I
gave the /boot, /var, and /usr partitions too much space and didn't give
/home in its own partition so / fills when users (i.e. me!) do something
requiring a large amount of space. It's something I have meant to fix
for a while - probably moving /home to /usr/home would do it but I don't
want to interrupt the process that urgently requires the disk space so
I'm looking for quick temporary patch up jobs to make some space. I
guess I'll have to kill a bunch of processes to free up /tmp anyway!
