Subject: guix-jupyter's ";;guix pin" doesn't support channels.scm?
Date: Wed, 13 Oct 2021 18:23:51 +0100 [thread overview]
Message-ID: <871r4on8ig.fsf@beadling.co.uk> (raw)
Hi all,
Reading:
https://gitlab.inria.fr/guix-hpc/guix-kernel/-/blob/68b525b241cf952940d4bf66e2697c2d1f3722e5/README.org
There is no explanation of how the ";;guix pin" command can pin multiple channels.
Looking at the source code it seems to only try to match the commit id against the contents of %default-channels:
https://gitlab.inria.fr/guix-hpc/guix-kernel/-/blob/341aecd8b4358b1b0a0c94235d7601f92c7b9942/guix-jupyter-kernel.scm#L551
My understanding is that %default-channels won't be augmented with any channels defined in /etc/guix/channels.scm or ~/.config/guix/channels.scm, which means it is impossible to pin any auxiliary channels beyond those defined as defaults.
I note if I run ";;guix describe" without ";;guix pin", all 3 channels are returned as per my /etc/guix/channels.scm - so by default it seems to take set itself using the channels.scm, but then only allows us to pin the main guix channel.
My question is how to I pin multiple channel definitions as part of my notebook?
Will running jupyter inside 'guix time-machine' with a channels.scm file
do this? The only problem I see with this is that we've created an
external file required to define how to run jupyter which breaks the
"everything defined inside the notebook" aim?
Cheers,
Phil.
