It seems better !

Thanks :)

I succeeded in booting the installer, I didn't try to install GuixSD on
eMMC for now.

I really doubt that it will succeed :(

Sure I see two viable use-cases for now :

* Build a functional system (mpd or prosody server for example) and
  write it on an external sdcard.

* Cross-build a functional system and write it on an sdcard too.
  It could be interesting because building a system image on a quite
  powerful ARMv7 board (I bought an Odroid XU4 for this purpose) takes
  between 3-4 hours.

Time is mostly spent in qemu machine copying files and in
guix-registering.

I don't think installing/guix pulling/guix system reconfiguring/ as we
do it on intel systems is really viable on those tiny ARM boards.

Thanks again and yes, it's the top task on my todo-list :)
