The current arrangement of service and socket units is sort of all over the place. Let's clean it up a little, roughly following the principles below: - socket units have implicit ordering deps (not to be confused with default ones which are subject to DefaultDependencies=) before associated service, so drop any explicit After= - If socket can be enabled, remember to link to it in service via Also= and Sockets= (the latter replaces Wants=). If the service Requires= socket however, Sockets= is omitted. - If socket is statically enabled, no need for service to pull it in - machined
