-# HOW TO USE
-# ```sh
-# $ sudo mkdir /nix/persist/private.new && sudo chown colin:users /nix/persist/private.new
-# $ sane-private-change-passwd /nix/persist/private.new
-# this should prompt you to enter a password for the new directory.
-# now all data in the original /mnt/persist/private has been re-encrypted, into /nix/persist/private.new/cipher
-# if the data on-disk looks reasonable, continue:
-# $ sudo mv /nix/persist/private /nix/persist/private.old
-# $ sudo mv /nix/persist/private.new/cipher /nix/persist/private
-# $ sudo rmdir /nix/persist/private.new
-# ```
