I used to automount on OSX by sudo vifs and adding a line like vault.local:/backup /Volumes/backup url auto,url==afp://;AUTH=No%20User%20Authent@vault.local/backup 0 0. But that no longer works on Maverick because the system deletes everything in /Volumes on wake/restart/something-or-other.
We are going to create a mount at /mnt/Resources. We need to edit the auto_master to tell it where the automount config for /mnt/Resources lives:
sudo vi /etc/auto_master
Now add this line at the top
