yes, it worked a lot so once you say watch it watches until you stop it, including through closing terminals, computer power off, etc. It should restart on reboot, but -- test it yourself and tell me if I'm wrong :)

  > unf watch

  # reboot
  > unf list

it should say watching on your directory still, if it stays crashed or something else. ping me at support at v1.co

Just one human, two machines at my home can't replicate all configurations...
