This is an interesting point; I would rather have been in favour of the second solution, assuming that it would also simplify the binary installation (everything is self-contained inside /gnu). Why do they need to be mounted separately? Could /gnu not be mounted keeping the access rights of the original file system? There is also a middle ground that would be possible: Move some of the content of localstatedir to /gnu; this would make sense for the sqlite database, for instance. Then it would be possible to copy /gnu from one system to another. On the other hand, there are quite a few more things in /var/guix, so maybe this is not really sensible. In any case, I am for implementing one of these two possibilities. Andreas
