I fail to see how moving the Aarch64 build slaves to Hydra in the short
term would constitute an "effort to keep Hydra on life support", nor how
this would hinder efforts to improve Cuirass.  I agree that we should
retire Hydra when Cuirass matures.

My proposal is not about helping Hydra, but rather about *using* Hydra,
our only sufficiently useful CI system right now, to make our Aarch64
port usable.  It currently isn't.

If anyone believes that I'm mistaken about our Aarch64 port being
unusable, then please help Benjamin Slade install Guix on his Aarch64
system.  I'd be glad to be proved wrong.
