Hello. systemd with hostnamed-fallback always fail to set hostname. The fallback is nice, but it's not working properly. I have minimal gentoo installation with systemd. Of course, I don't want to bloat it with polkit-spidermonkey-llvm-rust, so I added "hostnamed-fallback" use flag and rebuilt systemd and dependencies (by emerge -vuDU @world). Unfortunately I'm getting errors in log like: ------------------------------------- Mar 12 14:22:24 dbus-daemon[254]: [system] Activating via systemd: service name='org.freedesktop.hostname1' unit='dbus-org.freedesktop.hostname1.service' requested by ':1.1' (uid=192 pid=211 comm="/lib/systemd/systemd-networkd ") Mar 12 14:22:24 systemd-timesyncd[248]: Network configuration changed, trying to establish connection.

hostnamed-fallback workaround works only if dbus-broker is used instead of standard dbus implementation. By default, when dbus-broker is installed, it is not activated, so standard dbus implementation works perfectly as designed, but hostname doesn't work. Looking at the log entries and documentation it's hard to find what's wrong. In my PR https://github.com/gentoo/gentoo/pull/24514 I added check at postinstall stage. If hostnamed-fallback is used, but dbus-broker is not activated, emerge will print warning message with instruction how to fix it. I think this should help users to avoid the same problems as I have had.
The bug has been closed via the following commit(s): https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=aa6a892c022128dfe993ac2b0e0ef23600304a8b commit aa6a892c022128dfe993ac2b0e0ef23600304a8b Author: Karlson2k (Evgeny Grin) <k2k@narod.ru> AuthorDate: 2022-03-12 17:36:37 +0000 Commit: Mike Gilbert <floppym@gentoo.org> CommitDate: 2022-04-08 23:17:15 +0000 sys-apps/systemd: warn when dbus-broker is needed. Warn if hostnamed-fallback workaround is used, but dbus-broker.service is not enabled. This should give users a strong hint of what needs to be done.
