Actually, running guix-daemon in proot is not a problem - who cares
that the build system is slow ;)

If we can solve this we are set. Any idea why nix execv is not
running this script? I added some info to it and is simply not found.
It can't be a proot thing because I have been invoking builds etc.
already. I have a feeling I have seen this before.

If you read my document you'll see I have been running guix in proot
with success. I only want to use a different store now.
