My point is that ’Guix is unavailable’ is special and it appears to me
expected to raise an error. Other said,
1. if %default-guix-channel (or its mirrors) is unreachable,
then stop the pull; as it is currently done.
2. if an extra channel is unreachable,
then keep the last local revision of this channel
and try the others.
For sure, #2 can break the whole pull if something in the Guix channel
changed *and* the channel depends on this something. But we cannot do
more than raise an error.
Cheers,
simon
