Guix installer

About.

The script install.sh will do a couple of actions to try to make the GNU/guix installation more friendly, so, basically this README.org file will tangle the script, the power of emacs of course. So, while I was working in this “note” file, then I realized that I can use emacs and make a script.

Download and burn the iso.

I use the systemcrafter ISO.

1

sudo dd status=progress if=guix-installer-202106150234.iso of=/dev/sdb && sync

Install the OS.

Now with the Guix iso. Boot your laptop in it, and follow the instructions to install the OS, just ignore the warnings about the libre software, And stop in the part that you actually going to start the installation, and open another TTY:

1

Ctrl + Alt + f2
