Hi again, I managed to do it by putting this in my custom.el file.
(require 'org)
(org-babel-load-file
(expand-file-name "
init.org"
"~/.emacs.d/personal/"))
This seems to do the trick, however, it seems that it creates an init.el file tangled from the .org one; I guess this is expected though.
Thanks
best,
K.
