I think the concept of garbage collector roots should be clarified in
the manual somehow and linked to from 'Invoking guix gc'. Or it could
even go in that section.

I was surprised to find that the string 'gcroots' does not appear in the
manual.

In your case, things that are not garbage collector roots (that is, not
reachable from /var/guix/gcroots) could be considered orphans or
temporary. I agree the documentation should be improved.
