MOUNT_9P(8) System Manager's Manual MOUNT_9P(8)

mount_9p —
mount a file server using the 9P resource sharing protocol

mount_9p [-su] [-o mntopts] [-p port] [user@]host[:path] mount_point

mount_9p -c [-su] [-o mntopts] devfile mount_point

The mount_9p program is used to mount a file hierarchy served with the Plan 9 file sharing protocol: 9P. After the file system is mounted, the files on the remote host will be accessed using the credentials of the user named user and whatever UID the user happens to have on the remote server. If path is supplied, it is used as the mount rootpath on the remote host. path must be an absolute path.

The -c opiton enables to mount a file system exported by a VM host through a character device file devfile backed by the vio9p(4) driver. See vio9p(4) for more information.

By default mount_9p runs in the background with daemon(3). With the -s option mount_9p runs in the forground.

By default mount_9p follows the 9P2000 protocol. With the -u option mount_9p follows the 9P2000.u protocol that includes extensions to better support Unix environments.
