Using tmpfs to hold volatile state for RO or limited write media is
nothing new. Such sites normally have /var/run mounted as such and
/etc/resolv.conf as a symlink to an updateable location on tmpfs. And
when using dbus + dnsmasq + static /etc/resolv.conf no configuration
file needs updating.

resolvconf is a very good idea.
