[9fans] swap swap?

[9fans] swap swap?

[andrey mirtchovski]

hi,

how does plan9 turn on swap? i was just playing with some memory-intensive
stuff when it crashed with 'swap not configured' printed on the console.

i ran 'swap /dev/sdC0/swap' immediately and that solved my problem, but how
do i make it permanent? just put it in /rc/bin/cpurc?

I have this in /rc/bin/cpurc

if (test -e /dev/sdC0/swap)
	swap /dev/sdC0/swap

But beware, I've seen complaints about `not enough memory' in those
weird circumstances when swap was used a lot in our system. It's much
better to add more memory.

A further word of caution: make sure your cpurc binds #S into /dev
before using names like /dev/sdC0.

I added this to /lib/namespace a few weeks ago after we got
burned one too many times here, but I forgot to push it out.
It's out now.
