`-h, --help`	Display usage message.	man
`-o, --descriptors` num	Set the limit of the number of open file descriptors to num.	man
`-N, --no-nfs-version` mountd-version	This option can be used to request that rpc.mountd do not offer certain versions of NFS.	man
`-n, --no-tcp`	Don't advertise TCP for mount.	man
`-p, -P, --port` num	Specifies the port number used for RPC listener sockets.	man

`-v, --version`	Print the version of rpc.mountd and exit.	man
`-c, --apply-root-cred`	When mountd is asked to allow a NFSv3 mount to a subdirectory of the exported directory, then it will check if the user asking to mount has lookup rights to the directories below that exported…	man
`-g, --manage-gids`	Accept requests from the kernel to map user id numbers into lists of group id numbers for use in access control.	man
