Hello!
When changing display manager in the system configuration and invoking`guix system reconfigure`, the existing desktop environment will bekilled. If you invoked the command from within said desktop environment,the reconfigure command will be forcefully terminated.
If you're unlucky, this might happen during `grub-install`. Afterlogging in on a console and rebooting, this is what I got:
Toggle snippet (10 lines)
Welcome to GRUB!
Attempting to decrypt master key...Enter passphrase for hd1,gpt2 (<uuid>):Slot 0 openederror: file `/boot/grub/x86_64-efi/normal.mod' not found.Entering rescue mode...grub rescue>
It can be recovered by booting by copying /boot/grub/x86_64-efi/* from ahealthy system to the partially installed one.
I'm not sure how to mitigate this, since the DE restart is arguably afeature. A command analogous to `nixos-rebuild boot` might be of aid forthose of us aware of this problem.
