Use (require 'guix-autoloads nil t) instead.  Nowadays, the only thing
'guix-init' does is it requires 'guix-autoloads'.

I have no idea what it is used for (I don't have this setting in my
emacs config), but "-b" is probably should not be specified here.  If
you do:

1. M-: (require 'ediff-ptch)
2. C-h v ediff-patch-options

you'll see a note about "-b" option.

The rest looks good to me, I use pretty much the same configurations to
set up Guix (and emacs stuff) from git.
