Ok, that's fine, then.

Try (setenv "HOME" "/tmp") as Danny mentioned.

Yes, the licenses are correct now.

Only a matter of aesthetics, but you could split "-C" and "source" into
separate strings.

Put 'check on the same line as replace. In emacs, you can use
guix-devel-mode from emacs-guix to help you with indenting correctly.

You can drop the `and' function call, and just make it individual calls
to `mkdir-p' and `zero?'

Looking good so far! Only the check phase remains...
