bug#37254: [PATCH 0/4] Refactor (guix ci) and (guix import crate)

["Ludovic Courtès" <ludo@gnu.org>]

Hello,

Efraim Flashner <efraim@flashner.co.il> skribis:

There was room for improvement though:  :-)

“guix import crate schannel” doesn’t work on master.

I’ve pushed the whole series now.

Thanks for your feedback!
