It’s a matter of evaluating the etc/profile file that is generated for
every Guix profile.  Since you passed


to “guix environment” there will be a file


You can set all the environment variables it defines with

    source $GUIX_PROFILE/etc/profile

If you want a pure environment you can use “env”.  On our HPC cluster I
provide “activate” scripts like this one:

--8<---------------cut here---------------start------------->8---

prompt='\u@\h:\W \[\e[31;47;1m\][pigx]\[\e[m\] $ '

exec /bin/env - PS1="$prompt" \
                HOME=$REAL_HOME \
                LANG=en_US.UTF-8 \
                GUIX_LOCPATH="$profile/lib/locale" \
                CURL_CA_BUNDLE="/etc/ssl/certs/ca-bundle.crt" \
                /bin/bash --init-file "$profile/etc/profile"
--8<---------------cut here---------------end--------------->8---

It sets a few environment variables, recovers some variables that are
important, and then starts a sub-shell that uses the generated
etc/profile file as its init file.

Something like that might work for you.
