Hi,

I've rebased the patches to latest master and fixed some conflicts.

However, I'm unable to build the system on my Pinebook (aarch64 for native build).

./pre-inst-env guix system build gnu/system/examples/raspberry-pi-64.tmpl

The following derivation will be built:

Unfortunately the build log is not helpful uncovering the cause (at least to me).

I've also attempted to cross-compile the system (from x86_64) but there is at least one package that can't be build - guile-fibers-1.1.0. I've attached the build log as well.

Kind regards,
Petr
