#/debug (or, in RISC/os, /proc) is *NOT* your swap space.  It's a special
#type of virtual filesystem which presents a view of your running processes
#accessible through the file namespace.  If it's not mounted, you just can't
#use programs (like some debuggers and other tools) that access processes by
#opening them like files.  This has *nothing* to do with your swap space.

But the burning question is...

If your disk is partitioned so that /debug gets, say, 53meg, does that mean
that you only have 53meg of swap space, maximum?
