--- Comment #1 from David Herrmann <dh.herrmann at gmail.com> ---
hostnamed sets the kernel hostname itself, so there is little reason in
tracking it. We don't support other processes setting the kernel hostname
directly (and there is little reason for it), but only via hostnamed APIs.

Currently, hostnamed sends dbus notifications for *any* hostname change. That
is, if you're interested in a specific hostname, watch those notifications and
then either parse them are read the hostname via the gethostname(2) syscall.

Btw., I just noticed that we have the code to send notifications for "Hostname"
changes, but we lacked a vtable annotation. I fixed this [1], so you should now
get notifications for "Hostname" changes, too.
