Oh, true; two weeks of vacations and everything is forgotten.  :-)

Alright, well so be it.

Then I guess the next step is to stare at ‘guix size gdm’ in search of
ways to trim the closure.  It might not be that hard actually:

$ guix size gdm |head

Yup, we’ll see.

Closing this issue now anyway.

Thank you!
