But the point of Guix is: each user manages their own version, isn't it?

one central copy, because in any case, each user can run:

  guix time-machine -C <channels.scm> -- <command>
  guix time-machine --commit=<hash> -- <command>

so each user can install, remove, etc. any version of Guix (specified
by <channels.scm> and <hash>) independently of the version of "guix

Well, I am not sure to understand the aim of the configuration you want to.

I do not know how you could setup your non-standard usage of Guix.

Maybe you could try as root:

   sudo guix pull -p /usr

then place /usr in the correct paths (PATH, LIBRARY_PATH, etc.) for
each user.  However, it will be easy for one user to by-pass your
setup and use any version of Guix they wants:

   /usr/bin/guix pull -p /path/somewhere/to/user-home

then the user can correctly set up the paths so that "guix" will refer
to the one living at /path/somewhere/to/user-home/.

Well, from my understanding, you are trying to set up Guix in the
paradigm of classic package manager, not in its "philosophy".

I am not sure to understand what you mean.

Do the explanations help?
