[ Ah, indeed. Not sure why it's not in `mount` even though that page also
claims to have NFS-specific options. In any case, this confirms tht
soft mounts still exist. Thanks. ]

Indeed, but the OP's description of the behavior he's trying to get from
Emacs suggests maybe he'd be satisfied by a `soft` mount.

[ where "temporarily" can last a long time. ]
- buggy NFS (the server is up and exporting, the connection as well,
yet the NFS client stalls for some unknown reason).
