Arg, I ndeed I missed that. Nice point.

Neither do I , but I would not wagger it isn't... ;-)
However, from what I understand, the part between the '@' and the
'.service' is used to fill in the %I placeholder in the service file.
Since the console-getty.service does not have a placeholder, it is
hopefully not a problem that we create the console-getty at console.service
file...
Xavier, if this is the case, please say so in the commit log. If I wrote
bullsh!t, then please also say so, and then explain how your patch makes
it work.
In either case, I think it would make sense to indeed do as Peter
suggested, because even if your patch works, it's probably a trick and
could break in a future systemd release...
Regards,
Yann E. MORIN.
