Hi Maxime,

According to the documentation to get all the environment variables set
correctly you either need to manage your login shell with Guix Home or
do additional configuration of your shell:
https://guix.gnu.org/manual/devel/en/html_node/Configuring-the-Shell.html

From what I see you manage bash with Guix Home, so according to the
source code your bash_profile should look differently from what you've
posted and must contain `source ~/.profile` in it:
https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/home/services/shells.scm#n440

This line makes your login shell source .profile, which sources
setup-environment, which sources ~/.guix-home/profile/etc/profile, which
sets EMACSLOADPATH.

Additionally, I've built the home environment you provided and it
contains the code I mentioned above.

Make sure that ~/.bash_profile and ~/.guix-home/files/.bash_profile
point to the same file in the store.
