Hello Guix,

I had an issue yesterday.  After 'guix system reconfigure' I couldn't
boot, because there is no a menu entry in UEFI boot menu.

So, I solved this by following Gentoo wiki article¹.

Boot with LiveUSB XUbuntu 16.04.  Any distribution that could boot via
UEFI and provides efibootmgr app will work.

Create new boot menu entry:

    # efibootmgr -c -d /dev/sda -p 1 -L "GuixSD" -l "\EFI\boot\grubx64.efi"

Check created boot menu entry:

    # efibootmgr -v


I have a little question.

Does GuixSD overwrite this boot entry with efibootmgr or similar every
'guix system reconfigure'?

Thanks,
Oleg.
