Looks like I need to upgrade my Guix system to fix substitution ... but 
"guix system build" is currently failing, which needs [cycle!].


This time when doing "guix system build" I have a new error:

I haven't seen this ‘failed to alternative substitute for [...]’ before 
and it seems unrelated to #63634. There is also bad error reporting 
here: failing to find a substitute is not a form of ‘corrupted/damaged 
input’.


I'll do the usual tricks (*) to work-around for now, to get the fix in 
#63634 even though it doesn't fix everything.


(*): while :; do guix system build /etc/config.scm -M1; done

Greetings,
Maxime.

The one workaround I'd suggest is cleaning the guix-daemon's substitute
cache (/var/guix/substitute/cache). That alone should be sufficient to
work around any missing zstd nars.
