 We need to have /tmp be a tmpfs to save pointless NAND writes.

 Programs that need to store sizable things in a tmpdir should use
 /var/tmp, which will still be in NAND.

 There is a long-standing tradition of having /tmp in volatile and
 constrained storage (ie: ramdisks), so it is a bug for anything to write
 large files there. I mention this because I think it's worthwhile to run a
 quick check for users of /tmp to avoid unexpected breakage -- is olpc-
 update (ab)using /tmp when it should use /var/tmp?
