Mounts Network File System (NFS) exports as filesystem volumes. mount_nfs can take a large number of options, most of which offer knobs to tune the performance of NFS mounts. Only a few are described in the "Options" section; see the manpage for full details.
After an initial mount attempt fails, fork off a background process to continue trying the mount.
Make the mount interruptible, so that processes failing to access the mount can be terminated, instead of getting stuck in an uninterruptible state waiting on I/O.
Enable Kerberos authentication.
Specify a Kerberos realm to use with the -K option. Takes a realm name as an argument.
Takes -o options as listed in the mount manpage.
Make the mount soft, so that processes failing to access the mount eventually receive an error, instead of getting interminably stuck waiting on I/O.
Enable the use of TCP as the underlying network transport protocol, instead of the default UDP.
The hostname or IP address of an NFS server.
The pathname of the NFS export you wish to access.
The directory on which the filesystem is mounted.
