Hi,

kristofer@openmailbox.org skribis:

> I have working installation of GuixSD on my Macbook!

Nice, thanks for your feedback!

> GuixSD USB disk

> rEFInd bootloader - http://sourceforge.net/projects/refind/

Is it impossible to boot directly from the USB image on this machine?

I=E2=80=99m not familiar with GRUB=E2=80=99s EFI support.  Why do we need t=
he =E2=80=98loader=E2=80=99
and =E2=80=98options=E2=80=99 lines instead of just one =E2=80=98linux=E2=
=80=99 line?

Should be provide a field in =E2=80=98grub-configuration=E2=80=99 that woul=
d allow one
to choose an EFI installation?  This sounds similar to special-case for
Libreboot that was recently proposed.

Thanks,
Ludo=E2=80=99.
