Description Tom Yan 2015-10-10 16:22:11 UTC

I notice that when dbus is built with  --enable-user-session, dbus.socket will be symlinked in /usr/lib/systemd/user/sockets.target.wants/.

In this case the socket unit should be static since it does not need to be enabled explicitly.

Since the [Install] section in the service unit is only for aliasing, it should be gone as well.

Otherwise, dbus.socket will be marked as "disabled" in `systemctl --global list-unit-files`, which could be confusing.

P.S. If for some reason the change will be symlinking dbus.socket in /etc instead, Also=dbus.service is not necessary in dbus.socket since the [Install] section in dbus.service is only for aliasing, as mentioned above.

systemd experts: what's the preferred resolution for this one? Install the symlink and lose the [Install] section as Tom suggests?

For a system service I'd say "don't install the symlink and expect the distribution packages to enable it", but D-Bus is OS plumbing that is used by systemd on non-kdbus systems, so it's a bit special anyway; and distributions don't typically have infrastructure for enabling user services like they do for enabling system services, AIUI.

I'm not going to touch how this works in 1.10, because stable branches shouldn't contain surprises; but I'm happy to make it correct in 1.11, if we can agree what the most correct thing is (even if that requires distributors to change their packaging).

Lennart says we should indeed do that.

Fixed in git for 1.11.0.
