What do you mean by =C2=ABbu=

them!=C2=BB?  Do you mean keep the last revision locally known for this
channel?

I'm not sure what you're asking, because of the negatives.

With "but don't ignore [...] by [...]", I meant that, yes.

If you meant "don't ignore [...] by [...]", then no, with 'ignoring by removing', I meant, literally removing them.=C2=A0 Mor= e concretely, a situation like this:

  • In the channels.scm, two channels are declared: guix and guix-foo.
  • User does "guix pull"; Guix downloads the source code of guix and guix-foo.
  • Downloading guix failed (503).=C2=A0 As such, Guix decided to ignore the guix channel, by removing it from the list of channels to build. (The in-memory list I mean, I don't mean modifying the channels.smc file)
  • Guix tries building the guix-foo channel and installing it, without the guix channel.
  • This cannot work (the guix-foo channel uses modules from guix for basic stuff like G-exps, packages, coreutils, ..., and it was the removed guix channel that had things build-aux/build-self.scm which is required for pulling).

(It's not unlike double negatives! I first thought of the latter interpretation but on second thought you might have meant the former.)

Greetings,
Maxime.
