Let’s just set the ‘locale-libcs’ field in (gnu tests) so that it
contains a single libc.  WDYT?

Yes, but that’s necessary for “ssh -X”, so I think we consciously made
that choice long ago.

Comes from the Python plugin added in
452244e670467afe0e8ccdfb9ca2980d5a3b4694.  No idea what it buys us.

Ah would be nice to fix and add a #:disallowed-references flag there!

Yeah, that’s the price to pay.  :-/

Woohoo!

Yep, see my recent message on this topic.  :-)

Thanks,
