For the sake of reducing complexity and keeping supported systems as
close to one another as possible, would it be an option to keep using
2.0 for GNU/Hurd, like on the other systems?

That would entail changing make-bootstrap.scm to use 2.0 instead of 2.2
as a first step.  And yeah, it=E2=80=99d also entail another full rebuild, =
which
I=E2=80=99m sorry for, but I think this kind of simplification pays off qui=
ckly.

WDYT?

(I vaguely remember discussing it before but I forgot the outcome of the
discussion.  Apologies for that!)

Thanks,
