Hi! I've been trying to hack around the racket
build system(see attached) for some time now;
mostly using raco... The biggest problem I've
faced so far is that AFAICT, when you use raco to
install packages, racket updates some files from
where it's called(in guix's case store this is the
store where racket is in)--- and I don't think you
are allowed to do this. I've tried doing "raco
install <zipfile>", and also just doing "raco
install" from inside the directory.

The command for building:

--8<---------------cut here---------------start------------->8---
env 
GUIX_PACKAGE_PATH="/home/bonface/projects/guix-bioinformatics:/home/bonface/projects/guix-past/modules"
 ./pre-inst-env guix build racket-hello-racket -K
--8<---------------cut here---------------end--------------->8---

with the error:

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

And when troubleshooting:

--8<---------------cut here---------------start------------->8---
cd /tmp/guix-build-racket-hello-racket-0.0.1.drv-0

/home/bonface/guix/pre-inst-env guix environment \
--no-grafts -C racket-hello-racket --ad-hoc strace gdb

source ./environment-variables

$GUIX_ENVIRONMENT/bin/raco pkg install --no-cache \
--no-setup --ignore-checksums

--8<---------------cut here---------------end--------------->8---

Which works just fine since I'm updating files
inside $GUIX_ENVIRONMENT. Right now I'm looking
for ideas to experiment with to try to overcome
this, and the low hanging fruit is to successfully
build a hello-racket package with zero deps and no
tests.

To simply put it, AFAIU updating a package would
require racket to update it's references(either
links, and other references that I won't go into),
hence creating some form of "global state";
thereby if you use raco, every package updated
would lead to some update with racket's search
paths or dirs somewhere. Any ideas to overcome
this wall? (or anything I've got wrong somewhere?)
