I think we have a misunderstanding here. Do you mean access to the
releases of Guix as in what's on
https://alpha.gnu.org/whatever/the/path/to/guix/was, where the software
itself is released, or did you mean what we call 'binary substitutes' in
Guix, the packages which are build from the guix.git master which
feature the software (here software as in tor, perl, epiphany, gnupg,
Now that I'm reading your initial email again it reads as if could be
either or both. It would be good if you try to clarify this.

The torbrowser I am packaging initially is a 1:1 copy of what torbrowser
team is keeping in the git repository. Nix for example decided to
just patchelf the binary releases of torbrowser (the tar files found on
dist.torproject.org), this is not acceptable for the work for Guix.
So I'm trying my way with building from git tags. If there are other
people interested and willing to help (once I have something to debug),
I will share recipes / git repositories to work on it.
Furthermore the final package version for Guix will include fixes which
might be needed, similar to what icecat does to firefox esr, to include
it in Guix. This is of course no 1:1 torbrowser then anymore and must
not be described as such. It'll be interesting to see if at all it
differs in fingerprinting from torbrowser.
If for any reason you need the full 1:1 copy we can talk about this once I/we
are getting there, offlist or at least not on guix-devel at gnu.org.

I think HEADS (the linux-libre grsec devuan based blend) did this, or they
are working on it. I know for Guix, someone is working on SELinux. I
think if you are looking into getting a GRSec enabled kernel with
according policies, this must be answered by someone who knows more
about the core of Guix.
It might also be the case that I don't fully understand your plan. What
I read sounds like you are either mixing up Guix and GuixSD or as if
the differences between both need to be explained. It would be easier to
know the current state of the system, and where you want to go with this.
