From a296b0623eb23300751b8c571ad804884d1fbd4f Mon Sep 17 00:00:00 2001 From: Ross Burton Date: Tue, 5 Aug 2025 12:26:13 +0100 Subject: [PATCH] dbus: use the systemd class to handle the unit files Originally, the dbus recipe couldn't use the systemd class because there was a circular dependency between systemd and dbus. However, since systemd v209 in 2014[1] systemd hasn't needed libdbus, as it has it's own implementation of the client library. DBus does not use the systemd libraries, so there is no circular dependency. The dbus build was already was installing the service and socket files, so we are installing them again. Remove the installation of the units. Manually mask dbus-1.service by simply creating a symlink, instead of depending on systemctl and using an postinstall script.
