What to do with aliases?

[root at localhost ~]# systemctl -p Names -p Id --no-pager show dm.service
Id=prefdm.service
Names=display-manager.service prefdm.service dm.service
[root at localhost ~]# systemctl is-enabled dm.service
dm.service is not a native service, redirecting to /sbin/chkconfig.
Executing /sbin/chkconfig dm
[root at localhost ~]# echo $?
1

Well ...

dm.service is obviously enabled; even if it is enabled under different alias

BTW /etc/init.d/dm actually is enabled ... just in different run level.

In any case, whatever systemctl does, it probably needs be consistent

[root at localhost ~]# systemctl is-enabled display-manager.service
Refusing to operate on symlinks, please pass unit names or absolute
paths to unit files.

One is Names and another one is link.
