Just recently I noticed that our installation tests had starting failing
with that exact same ‘grub-install’ error that was mentioned:
https://ci.guix.gnu.org/build/3708453/details
Cuirass says the culprit is in the 4003c60..daab3da, which indeed
includes the e2fsprogs update to 1.47.0.
Have you tried upgrading GRUB? I see ‘guix refresh grub’ finds a new
version. If fixing the bug is what it takes, we should do that.
Thanks for the investigation!
Ludo’.
