Not having it on tmpfs has the same memory implications.  Remember that
the "writable" area of the live image filesystem is handled by the
device-mapper snapshot.  And writing to those blocks for /tmp has worse
implications longer term

With Snap2, there's support for automatically enabling a swap file found
at LiveOS/swap.img and livecd-iso-to-disk can take a --swap-size-mb
argument (analagous to --home-size-mb)
