Like you say, on Hydra-style setup this could be a problem: the
front-end machine may have --max-jobs=0, meaning that it cannot perform
builds on its own.
So I guess we would need a command-line option to select a different
behavior. I’m not sure how to do that because ‘guix offload’ is
“hidden” behind ‘guix-daemon’, so there’s no obvious place for such an
option.
In the meantime, you could also hack up your machines.scm: it would
return a list where unreachable machines have been filtered out.
