Changing the way one configures the hostname because one or a few
packages A) need this knowledge, and B) hardcode /etc/hostname is not
worth changing the canonical way to update it and getting people to
change their habits.

It makes a bit more sense to rely on previous configuration
(/etc/conf.d/hostname) and write a tiny 'script' that populates
/etc/hostname. bash could do it (naively) in two lines:

source /etc/conf.d/hostname
echo "$hostname" > /etc/hostname

The 'multi-distro standard' is du jour at best and imo not a compelling
reason to follow.
