/proc is a seperate filesystem.  if you give tar the --one-file-system,
it will be excluded.  tarring it up is kind of pointless anyway, since
only a snapshot of it's outputs is preserved, and restoring it does not
producce a functional proc filesystem.

note, just for giggles, that you can mount a proc filesystem anywhere.
eg., mkdir /tmp/foo && mount -t proc none /tmp/foo.

but above /dev, i just did a fast test, tar -cpf /tmp/dev.tgz /dev/,
and tar did bitch about socket /dev/log ... not sure if that's a
problem or not.  but i've never notied any negative results from
using the technique in practice.
