Heya, just wanted to mention that systemd git now as a tiny daemon "hostnamed" which is started on demand via dbus, and whose purpose is exactly three things: provide a PK authenticated way for UI tools to change the hostname, for sending out change signals when the hostname changes and finally to maintain a "pretty" hostname (i.e. "Lennart's PC" instead of "lennarts-pc") and an icon for the local machine. I expect this to be used very soonishly in Avahi, NM, Bluetooth and in th GNOME3 configuration tools.
More information on this you find here: http://www.freedesktop.org/wiki/Software/systemd/hostnamed All of this are pretty desktopish features. That's why it is pretty easy to rip it out: just don't install hostnamed and its service file, and it is gone, as if it never was added in the first place. The configuration files for hostnamed (/etc/machine-info) are carefully separated from the essential hostname config file /etc/hostname to make this easy. At this point we have collected a few components of systemd that are of little or no use on embedded systems. To mind come here hostnamed, the binfmt handling, the console handling or even readahead. All of these components can be easily ripped out as they are not handled in PID 1 itself. However, you currently have to do so manualy: remove the binary from /lib/systemd and remove the matching unit files from /lib/systemd/system. I'd be willing to merge a patch to make these things configurable at compile time via ./configure switches. In general I am not a big fan of conditional compilation, but here are the rules by which I'd be willing to merge a patch: * They don't litter the code with #ifdefs. Littering makefiles OTOH is OK. * Everything defaults to on (i.e. the desktop build should be the default) * We only make the parts optional that make sense to be optional, instead of support a gazillion of different options just for the sake of having options. i.e. a good start is to make only the four components listed above optional, and maybe very few on top of that.
