Re: /tmp in swap space

Disk space is dirt cheap and getting cheaper all the time. Plus, there
could be a reliability concern here. If a program goes wild and fills /tmp
(which just happened to me last week btw), I wouldn't want my machine to
crash because it couldn't swap.

Wouldn't it be difficult to figure out disk space requirements for this
configuration? It seems like if I knew that at times I needed 100MB for
/tmp, and 100MB for swap, I'd be forced into making sure there was 200MB
available in /tmp if the two shared that area.
