On the standalone system, right?

Is ‘pam env’ needed at all if /etc/profile and /etc/zlogin are provided
anyway?

OK.  It would be best to have $HOME/.guix-profile/bin in PATH installed
by /etc/{profile,zlogin}, though, so that it works out of the box.

OK.

Thanks for the very good summary!  I never had this clear an
understanding of all this.

Would you like to submit a patch?  The relevant parts are in (gnu
system) for /etc/profile, in (gnu system shadow) for the .bashrc
template, and in (gnu services base) for the PAM settings of the ‘login’
command.
