 .Fn VFS_MOUNT
 initialises the mount structure for the mounted file system.
 This structure records mount-specific information for the file system and
 records the list of vnodes associated with the file system.
 This function is invoked both to mount new file systems and to change the
 attributes of an existing file system.
-If the MNT_UPDATE flag is set in
-.Em mp-\*[Gt]mnt_flag
-then the filesystem should update its internal state from the value of
-.Em mp-\*[Gt]mnt_flag .
+If the flag MNT_UPDATE is set in
+.Em mp-\*[Gt]mnt_flag ,
+the filesystem should update its state.
 This can be used, for instance, to convert a read-only filesystem to
 read-write.
-If the MNT_UPDATE flag is not specified, then this is a newly
-mounted filesystem.
+The current attributes for a mounted file system can be fetched by
+specifying
+.Dv MNT_GETARGS .
+If neither
+.Dv MNT_UPDATE
+or
+.Dv MNT_GETARGS
+are specified, a new file system will attempted to be mounted.
