RequiredBy missing in rclone-mount.service

[reaperfromhell]

When registering the rclone-mount.service I get this:

The unit files have no installation config (WantedBy, RequiredBy, Also, Alias settings in the [Install] section, and DefaultInstance for template units). This means they are not meant to be enabled using systemctl.

Solution: add RequiredBy=plexmediaserver.service to the [Install] section in rclone-mount.service
