* When we activate a descriptor in nix-switch, remember its hash.
This allows us to find out all `live' packages on the system by
doing
nix closure $(cat /nix/var/nix/links/*.hash)
which will print out the activated configurations and all packages
referenced by them. We could then garbage collect unused packages
by deleting the difference between `nix listinst' and the set
returned by `nix closure ...'.
