Also note that you can now use this specification:
--8<---------------cut here---------------start------------->8---
(list
(specification
(namee "my-pkgs")
(build '(channels my-guix-packages))
(channels
(list %default-guix-channel
(channel
(name 'my-guix-packages)
(url "https://github.com/methuselah-0/my-guix-packages.git"))))))
--8<---------------cut here---------------end--------------->8---
to have Cuirass build all the packages in your personal channel and rely
on the build farm at https://ci.guix.gnu.org to build all the other
packages.
Thanks,
Mathieu
