Hello!

These patches address two related issues:

  • The first one adds ‘-q’ to ‘pull’ and ‘time-machine’ to
    instruct them to ignore the user/system ‘channels.scm’ file.
    That way, a command like the following is guaranteed to have
    the same semantics regardless of available config files:

      guix time-machine -q --commit=v1.2.0 -- build hello

    This issue had been raised in
    <https://issues.guix.gnu.org/63726>.

  • The second one lets users do things (in Bash) like:

      guix time-machine -C <(echo %default-channels) -- …

Feedback welcome!

Ludo’.

  pull, time-machine: Add '-q' to ignore channel files.
  ui: 'load*' accepts /dev/fd/N files pointing to a pipe.
