Ah, it shouldn't be that much of a problem then. Famous last words, but I guess
I'll be doing some hacking to get GuixSD on ARM then! No promises. :)

I agree GRUB with ARM support would be better, though from my experience it's
still in its infancy. I've managed to get GRUB executing on my Novena board but
I've still had issues having it actually boot anything, eventually I gave up
since my use case was solved by something else. So unfortunately until that's
ironed out (and supported on more boards), I think U-Boot will have to make do
for now. I suppose it's also good hygiene to support more booting methods too.

I much appreciate the reply and sorry for opening a bug report on this rather
than posting to -devel or help-. I'll probably have a ton of bug reports and
patches down the line as I get GuixSD on to my T400, so I'm now drinking from
the firehose of all three mailing lists. :)

Cheers,
Jookia.
