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! Link on the issue tracker: https://issues.guix.gnu.org/72457 Thanks!!
