Subject: GNOME 3.4 will rely on hostnamed, localed, timedated D-Bus API
Date: Fri, 27 Jan 2012 00:56:25 +0100

GNOME 3.2 contains code to change:
 - system hostname
 - date & time settings (time, timezone, etc)
 - system locale

As there is no standard across distributions, GNOME detected the
distribution and for a few distributions, was able to change above
settings.

Starting with GNOME 3.4, GNOME will rely on the following D-Bus APIs
provided by the following daemons:
 - hostnamed
 - localed
 - timedated

These daemons are included in the systemd tarball. For the D-Bus API
reference, see the links at the end of this email.

Recommendation:
 - systemd only systems: ensure these daemons are packaged and running
 - systemd+sysvinit systems: put these daemons in a separate package and
   ensure they are running under both init systems. They do not rely on
   a running systemd.
 - other init systems: Please write a _new_ daemon to provide this
   functionality. The D-Bus API is really simple and instead of patching
   hostnamed/locald/timedated to support other distributions/init
   systemd, the recommendation is to just write a new daemon which
   implements the D-Bus API.
   Alternatively, (if these daemons do not need to be patched) only
   compile and package the hostnamed, localed and timedated from the
   systemd tarball.

Note: Ubuntu has written a daemon implementing the hostnamed and localed
D-Bus interfaces.
