[h8d13]

• no behavior change, simply rename the label

from polkit => systemd-logind

[h8d13]

On a correctness note: since polkit has no [Install], and so enabling it creates no symlink into .wants

Is enabled through the first D-Bus call. So I believe we could simplify further.

[h8d13]

In a fresh chroot:

$ systemctl --root=$R enable polkit
The unit files have no installation config (WantedBy=, RequiredBy=, UpheldBy=,
Also=, or Alias= settings in the [Install] section, and DefaultInstance= for
template units). This means they are not meant to be enabled or disabled using systemctl.

Possible reasons for having these kinds of units are:
• A unit may be statically enabled by being symlinked from another unit's
  .wants/, .requires/, or .upholds/ directory.
• A unit's purpose may be to act as a helper for some other unit which has
  a requirement dependency on it.
• A unit may be started when needed via activation (socket, path, timer,
  D-Bus, udev, scripted systemctl call, ...).
• In case of template units, the unit is meant to be enabled with some
  instance name specified.
