Never figured this out, seems it was the chroot issue, and maybe not
running garbage collection when I thought I was. Sorry I don't have any
logs.

I successfully got both the guix-daemon and the nix-daemon running on
the same machine through nix's configuration syntax.

Unfortunately, there is something wrong with how it uses acl, as it
warns me every time and then re-builds the world. Just installing guix
this way as it stands took 10+ hours of compute on an 8 core xeon with
32 gigs of ram.

So.. I need to figure out the substitutes issue (which mark_weaver on
irc rightly pointed out requires the second daemon in /gnu to have all
the package derivations match), and I think maybe my sysconfdir gets set
incorrectly.

Now if only I had fully free hardware so I could hack on guixsd more
easily.. but other than that, I'm very close! Redankon!
