Subject: ‘guix shell -CW’ provides a
 Guix command without extra channels
Date: Mon, 23 Oct 2023 18:26:10 +0200

‘guix shell -CW’ dismisses extra channels available in the original
Guix, as illustrated by this example:

$ guix time-machine -C <(echo '(cons (channel (name (quote guix-hpc)) (url "https://gitlab.inria.fr/guix-hpc/guix-hpc.git")) %default-channels)') -- shell -CW coreutils -- guix describe

This is due to the fact that ‘-W’ (‘--nesting’) is implemented by adding
the outer ‘guix’ to the container’s profile, without also adding its
companion profile entries (those that provide channels).

Actually, the original profile, which contains ‘guix’ and its channels,
*is* available in the environment:

The problem is the extra profile layer that confuses
‘current-channel-entries’ in (guix describe).

Oh.  Naive remarks.  The ’guix’ in the manifest points to the correct
one with both channels.

Well, what appears to me weird is that the ’guix’ I type is incorrect
but points to a correct one.

Well, another way to express,

        This is due to the fact that ‘-W’ (‘--nesting’) is implemented by adding
        the outer ‘guix’ to the container’s profile, without also adding its
        companion profile entries (those that provide channels).

is to note that the manifest file is incorrect and does not contain the
outer manifest file, right?

Hello!

I’m glad to report that this bug is fixed by
c90a4e8dcd6ac650392ffcc039273baf145aa3cc.

In these examples, you can see that all my channels are present, both in
a bare-bones ‘shell -CW’ (where bin/ is a direct symlink to the ‘guix
pull’ profile) and in ‘shell -CW coreutils’ (where bin/ fuses that of
coreutils and that of guix):
