Re: Access to nongnu channel

[Timothy Washington <twashing@gmail.com>]

Hey Marek,

I should have updated this earlier. But I did solve this problem with a
cleaner `packages` declaration.

(packages
 (append
  (map specification->package
       '("nss-certs"
         "gcc-toolchain"
         ...))
  (list my-package)
  %base-packages))

Thanks for the feedback. Indeed, for me this is an exercise in learning
Guix and developing my understanding of its modules.

Cheers
Tim
