The unmount.sh script has been working great in testing here.
I’ve added unmounting of sshfs volumes though I can’t test it ’cause I don’t have MacFUSE installed.
I highly recommend running the script from a launchd process as this provides for better logging. Lingon is great for setting this up and I’ve even got a sample file to use.
Still testing but if this rises on anyone’s radar and you want to play…
