The main change here is a patch of SLiM to tread a log file of /dev/stderr specially in that it now uses std::cerr instead of a file for logging. This allows us to set the logfile to stderr in NixOS for the generated SLiM configuration file and we now get logging to the systemd journal. Signed-off-by: aszlig <aszlig@redmoonstudios.org>
