RP and myself are still arguing over this so I thought I'd make my
argument on the list for debate.

Updating /etc/hosts is being done with a postinst in netbase simply
because /etc/hostname is contained in the base-files recipe. I
advocate just moving the creation of /etc/hosts to base-files along
with /etc/hostname, then base-files can write both files at the same
time.  There's already a dependency on base-files from netbase so
there will be no change in the rootfs, a file will just move between
packages.
