And this is what I saw, logging in as 'root' graphically, starting xterm
and issuing:

--8<---------------cut here---------------start------------->8---
root@komputilo ~# echo $PATH
/run/setuid-programs:/root/.config/guix/current/bin:/root/.guix-profile/bin:/run/current-system/profile/bin:/run/current-system/profile/sbin
--8<---------------cut here---------------end--------------->8---

Seems to be alright.

Could be tested with a nice system test ...

What would the system test look like?

1. Login using the login manager (difficult unless using autologin --
I've tried).

2. Open a terminal, run 'echo $PATH' and run the OCR on it?  That
doesn't sound too great.

I've pushed the series for now, feel free to experiment with it!

I thought there would have already been some similar system test for another login manager, but apparently this is not the case, nevermind.
