bug#47329: efibootmgr failed to register the boot entry: Input/output error

[David Dashyan]

Dear Guix,

I ran 'guix system reconfigure' yesterday and it failed during
bootloader installation. I couldn't load system afterwards.

Running 
> sudo efibootmgr --create --disk /dev/nvme0n1p1 --part 1 --loader \
> '\EFI\Guix\grubx64.efi' --label Guix
has same effect on guix system, but works fine when runned in ubuntu
live cd.

I don't get why it complains that there is "no space left on device"
though.

output of `df -h` contains:
> /dev/nvme0n1p1         548M  212K  548M   1% /boot/efi

Haven't woked out how to fix it manually, just keep suspending for now :)
