Move D-Bus conf file to $(datadir)/dbus-1/system.d

[worldofpeace]

Since D-Bus 1.9.18 configuration files installed by third-party should
go in share/dbus-1/system.d. The old location is for sysadmin overrides.

Do you have a link to docs about this change?

[worldofpeace]

See https://dbus.freedesktop.org/doc/dbus-daemon.1.html CONFIGURATION FILE

The standard system bus normally reads additional XML files from /usr/share/dbus-1/system.d. Third-party packages should install the default policies necessary for correct operation into that directory, which has been supported since dbus 1.10 (released in 2015).
The standard system bus normally also reads XML files from /etc/dbus-1/system.d, which should be used by system administrators if they wish to override default policies.
Third-party packages would historically install XML files into /etc/dbus-1/system.d, but this practice is now considered to be deprecated: that directory should be treated as reserved for the system administrator.

How do I test this? Does Pluma's date/time plugin get its information from this and provide a valid test, or does something else use it? The panel clock seems to work the same even if I disable this plugin in dconf-editor and restart m-s-d

I believe the .conf file that is installed is https://github.com/mate-desktop/mate-settings-daemon/blob/f58866e5d85915ba8e957cd0c6054c392f9d3ffa/plugins/datetime/org.mate.SettingsDaemon.DateTimeMechanism.conf

That conf file says

<!-- Only root can own the service -->

<!-- Allow anyone to invoke methods on the interfaces -->

So you have to check if root owns org.mate.SettingsDaemon.DateTimeMechanism and if anyone can invoke methods on the interface. Probably could test with d-feet.

I have no idea what d-feet is, but thanks for the instructions. Will leave this for someone who knows what they are doing for a proper test. Might get to a go-nogo "does it function" test but out of time tonight.

d-feet is a dbus debugger

Pretty useful tool to play around with dbus as you'd need to here.

[lukefromdc]

I can verify that /usr/share/dbus-1/system-services/org.mate.SettingsDaemon.DateTimeMechanism.service appears with this
While I do NOT know enough about debus to understand what would happen if this did not work, I can verify that restarting mate-settings-daemon, then mate-panel does not create any problems on changing the system time or displaying the time in the panel.

Someone who knows what this plugin is doing needs to review this

This one is wrong, see #303.
If you want to change the default please do in configure.ac.

[worldofpeace]

Didn't notice that, will PR a default change after that is merged 👍
