The systemd_conf_t type needs to be added as default file context for plain
files with the .conf suffix, for .conf.d directories in /etc/systemd,
/run/systemd, and /usr/lib/systemd, and for plain files and symlinks
in those directories. The /usr/local/lib/systemd directory is a subject
of file equivalency rules.

CHANGES WITH 256-rc1:
General Changes and New Features:

• Various programs will now attempt to load the main configuration file
  from locations below /usr/lib/, /usr/local/lib/, and /run/, not just
  below /etc/. For example, systemd-logind will look for
  /etc/systemd/logind.conf, /run/systemd/logind.conf,
  /usr/local/lib/systemd/logind.conf, and /usr/lib/systemd/logind.conf,
  and use the first file that is found. This means that the search
  logic for the main config file and for drop-ins is now the same.
