mount - keep track of remotely mounted filesystems
The mount protocol is separate from, but related to, the NFS protocol.
It provides all of the operating system specific services to get the
NFS off the ground -- looking up path names, validating user identity,
and checking access permissions. Clients use the mount protocol to get
the first file handle, which allows them entry into a remote filesys-
The mount protocol is kept separate from the NFS protocol to make it
easy to plug in new access checking and validation methods without
changing the NFS server protocol.
Note: the protocol definition implies stateful servers because the
server maintains a list of client's mount requests. The mount list
information is not critical for the correct functioning of either the
client or the server. It is intended for advisory use only, for exam-
ple, to warn people when a server is going down.
