nix-store -q --roots / --gc --print-roots: Print temporary / in-memory roots
For example,

  $ nix-store -q --roots /nix/store/7phd2sav7068nivgvmj2vpm3v47fd27l-patchelf-0.8pre845_0315148
  {temp:1}

denotes that the path is only being kept alive by a temporary root
(i.e. /nix/var/nix/temproots/). Similarly,

  $ nix-store --gc --print-roots
  ...
  {memory:9} -> /nix/store/094gpjn9f15ip17wzxhma4r51nvsj17p-curl-7.53.1

shows that curl is being used by some process.
