I think the right place for tiny mini-daemons like that is probably
systemd. Since MeeGo is using that too this should be fine for you guys

We already have a tiny daemon to deal with changing hostnames, and
pretty hostnames/icon names, while guaranteeing that it always stays
resolvable. My next steps are to fix locale and time/timezone like this

conmann also does geoloc? Is there something it doesn't do? Sounds
almost as crazy as systemd ;-)

Well, since you guys use systemd anyway, we might just ship it as
systemd component. But yeah, we probably need to get the story regarding
geoloc right before we do that.

Urks, so it seems to actively compare the /etc/localtime file with all
possible candidates. That's kinda evil.

I think it is time to introduce /etc/timezone or so which includes the
pretty name. Or maybe use a symlink for /etc/localtime, which would
allow us encode that info in the symlink path. And then write
/etc/timezone only for those crazyfolks who want to stick /usr on a
separate partition.
