With either of these suggestions, when you run out of space on one
partition, you'll have plenty on some other partition (probably / in
this case, unless you're putting /tmp there, which is a Bad Idea).
How can you possibly guess how big your /var file system will become?
I would recommend:
50MB /
256MB swap (don't forget that!)
rest /usr
Then create symlinks for /tmp, /var and, if you need, /home. If you
need to restrict growth of a specific file system, use quotas.
If your disk is bigger than your backup tape, make enough equal-sized
partitions so that each fits on a single tape.
