mount a 7th Edition(V7) File System
  
    | mount_v7fs | [ -Bbyte-order]
      [-ooptions]
      special node | 
The mount_v7fs command attaches the 7th Edition(V7) File
  System on the special device on to the file system tree
  at point node. Both special and
  node are converted to absolute paths before use.
This command is normally executed by
    mount(8) at boot time. The
    options are as follows:
  - -Bbyte-order
- Specify the metadata byte order of the file system. Valid byte orders are
      ‘be’, ‘le’, and ‘pdp’. If no
      byte order is specified, the file system is mounted in host byte
    order.
- -o
- Options are specified with a -oflag followed by a
      comma separated string of options. See the
      mount(8) man page for
      possible options and their meanings.
Amount_v7fs utility appeared in NetBSD

The v7fs support is still experimental.
