From FreeBSD 5.5 (the earliest I can check readily)
fstab(5)
The fourth field, (fs_mntops), describes the mount options
associated
with the file system. It is formatted as a comma separated list
of
options. It contains at least the type of mount (see fs_type
below) plus
any additional options appropriate to the file system type. See
the
options flag (-o) in the mount(8) page and the file system
specific page,
such as mount_nfs(8), for additional options that may be
specified.
So the fs_type (rw, ro, etc.) has always been documented as
obligatory, though in slightly less than obvious wording.
