Call for testers for bootloader subsystem rewrite!

[Lilah Tascheter]

Hey!

I just submitted a patchset containing a full rewrite of Guix's
bootloader subsystem, as in its current state, it was only really meant
to support GRUB. Seeing as we support a large variety of bootloaders,
and a bug in this subsystem could be disasterous, I figured I'd ask for
testers here.

So, anyone willing to throw an experimental patchset at some
(recoverable!) hardware, please test it out and tell me any issues you
encounter!

Thanks!!
