Historically, NFS is deployed on systems with static network configurations that are supposed to be set up before the NFS utilities come into play.  As Bruce suggested, perhaps this design assumption needs to be revisited.

program accesses the autofs mountpoint before the VPN is up? Wouldn't
autofs try to mount the NFS share right away and thus with a broken
