I wonder why the wiki does not mention "file:" URIs.
  $ man sources.list
says

  "file
   The file scheme allows an arbitrary directory in the file system to
   be considered an archive. This is useful for NFS mounts and local
   mirrors or archives."

Possible benefits of "cdrom:" could be that you do not have to give the
relative path from ISO root to the /pool directory and that you may get
an opportunity to plug and mount a new USB stick if the desired file is
not found in the mounted ISOs.

It would be helpful if somebody with sufficient experience would write
something about the choice between "file:" and "cdrom:" into the wiki.


Have a nice day :)
