[PATCH 1/2] dbus: build with systemd support

[PATCH 1/2] dbus: build with systemd support

[Andrew Shadura]

It's good to have the extra functionality, such as seat support
provided with systemd support. Not least of all to support
systemd user-sessions.

This commit also changes references to the system unit path
from ${systemd_unitdir}/system to ${systemd_system_unitdir},
a new variable provided by bitbake.

What is the impact on this if someone is using systemd but doesn't want
user sessions?  Should we enable it if the DISTRO_FEATURES contains systemd
by default?

It is okay to use systemd and not use user sessions. Possibly, we want
to enable it by default in the future, but it should be okay to have it
disabled for now unless it's switched on from elsewhere.

I've tried this out in combination with the D-Bus 1.10 update patches.
It's perhaps worth pointing out that user sessions only work in
combination with pam.

I also found that one minor fix was needed in
meta/recipes-core/dbus/dbus_1.10.2.bb. Andrew, Ross, feel free to just
squash that into the pending patch.

But overall it looked good, so I'd love to have this in OE-core.

commit 5b32e63f9e37492cef8de7aabfae562ab072b510
Author: Patrick Ohly <patrick.ohly@intel.com>
Date:   Fri Jan 8 15:34:50 2016 +0100

    dbus_1.10.2.bb: fix path to systemctl
    
    When compiling with systemd, pam and user sessions, the resulting
    /usr/lib/systemd/user/dbus.socket ensures that the right
    DBUS_SESSION_BUS_ADDRESS gets put into the environment when logging
    into the system.
    
    The default configure behavior is to look in the PATH, which picks up
    the tool from the host sysroot. We need to override that so that the
    final location on the target is used instead. This is only relevant at
    the moment when enabling user sessions, but it makes sense to fix the
    value in all cases.

Yes, systemd doesn't depend on dbus any longer unless explicitly
enabled, as it uses its own dbus library.

Your patch is against D-Bus 1.10.2, which is not yet in OE-core master.
I adapted the patch to the current D-Bus 1.8.20, but there the
advantages turned out to be (IMHO) fairly minor: it only adds logging
via journald.

socket activation via systemd already works even without
--enable-systemd, because the recipe explicitly installs the systemd
unit files and the code itself supports it also without
--enable-systemd.

But I like your patches, so perhaps including D-Bus 1.10.x (1.10.6 is
the latest stable release) can be considered for the next OE-core
release?

This patch is supposed to be applied after other series of mine adding
1.10.2, see <http://patchwork.openembedded.org/patch/108237/>.
