02/09: shell: ‘--development’ honors ‘--system’.

[guix-commits]

civodul pushed a commit to branch master
in repository guix.

commit d98a0203b733316a8a5c9440469dfdd10fc9613f
Author: Ludovic Courtès <ludo@gnu.org>
AuthorDate: Wed Dec 6 17:55:49 2023 +0100

    shell: ‘--development’ honors ‘--system’.
    
    Fixes a bug whereby ‘package->development-manifest’ would run with the
    wrong system in mind, leading to errors like this:
    
      $ guix shell -s i586-gnu -D shepherd --no-grafts
      guix shell: error: package linux-libre-headers@5.15.49 does not support 
i586-gnu
    
    * guix/scripts/environment.scm (options/resolve-packages): Define
    ‘system’ and pass it to ‘package->development-manifest’.’
    * tests/guix-shell.sh: Test it.
