Automount and unmount

[dnanian]

I mean the script should spawn a process and immediately exit: that process should sleep 30 seconds or so and then eject.- I believe I've posted examples of this elsewhere on the forum.

You'll need to add the authentication to the keychain, and that should be remembered (I'm assuming that the alias manager, which handles this, will know what to do -- we don't "remember" it ourselves, it does.)
