Hi Philip,

Yes, changing /etc/profile.d/guix.sh sounds better: it allows us to
provide a solution specifically for foreign distros.

This file is created by ‘etc/guix-install.sh’, the installation script
given at <https://guix.gnu.org/manual/en/html_node/Binary-Installation.html>.

Yes, that too!  We should change it so that it checks
~/.guix-home/profile and ~/.guix-profile (in that order) and picks the
right one.

Would you like to give it a try?

Thanks,
Ludo’.
