sudo systemctl enable ly.service - The unit files have no installation config

[simonfogliato]

When the following command is run:

sudo systemctl enable ly.service

Then the system returns a note.

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.

@simonfogliato This should be fixed by #623.

Which systemd version are you on? This was an issue with a recent systemd version: systemd/systemd#33411

[simonfogliato]

This is now fixed for me using Arch Linux:

• systemd 256.4-1
• ly 1.0.0-2
