bug#70954: No 'guix pull' substitutes for foreign distros?

[Nigko Yerden]

> I had not understood that you used the --commit option, sorry for the
> misunderstanding.
Technically I wasn't because at the time of experiment 08360a2cd
was the latest commit (not only the latest commit with substitutes).

> Foreign distros are not treated specially, but configuration for

Sorry, I couldn't find any mention of substitute authorization at [1].
On system B substitute public keys were configured according to [2].
I have checked the content of /etc/guix/acl file. All keys are there.

> Could you try “guix pull -q” to disable any other channels?
Sure! Here are the final parts of the outputs (after the words
"The following derivations will be built:"):

On system B (foreign distro):
$ guix pull -q --commit=08360a2cd0f1c447c9ad25bef8ed317abcdb0c91

It looks like these 'guix pull' derivations (not only 
guix-packages-base-modules.drv)
are almost completely different on system A and B.
