Hi Tobias,
As reported by oscar123123 on irc, this broke guix pull
To reproduce:
--8<---------------cut here---------------start------------->8---
guix pull --commit=a23091880d4dc6115acbfa3b7ef09d731fc5abb0
--8<---------------cut here---------------end--------------->8---
Tobias reverted the commit (thanks!).
I found this test to also show the failure.
--8<---------------cut here---------------start------------->8---
make check TESTS=tests/guix-system.sh
--8<---------------cut here---------------end--------------->8---
It turns out that this test creates a grub bootsloader with #f for
config.
Attached is a new version of the patch, that is robust against this;
this being the difference:

This fixes make check and I also tested that

now succeeds.
