So this says to me that having two ways of creating files in volatile
locations is stupid.  Should we just split out populate-volatiles from
initscripts into it's own package so it can be used by pure systemd
images, and split out systemd-tmpfiles so it isn't enabled by default?
 This patch solves the issue for resolvconf but there are plenty of
other recipes that don't install files/postinst for both
populate-volatile and systemd-tmpfiles.
