- I want to present a subset of devices to a chrooted devfs.
- I want to give a different set of permissions than the default.
- I want to be able to call a device by a different (symbolic name) without
  using symlinks.
- I want to prevent access to the device completely by not providing a device
  node.
- I want to preserve those changes across boots.
- I want to be able to move all my disk devices to a subdirectory.
