The org.freedesktop.Flatpak user D-Bus service isn't just used by flatpak(1) or applications running as Flatpaks. It's also used by toolbox(1) for similar reasons: * To keep various configuration files inside the container synchronized with the host * To let the container request certain commands to be run on the host The org.freedesktop.Flatpak D-Bus service itself doesn't need much in the way of dependencies, but inherits a lot of unused shared library linkages through the libflatpak-common.la convenience library. Removing these unused shared libraries reduces the footprint of toolbox(1) for those who care about such things. eg., Fedora CoreOS. This commit brings down the number of shared libraries to 19 from 62. Closes: #3052 Approved by: alexlarsson
