NULLFS(5)		      File Formats Manual		     NULLFS(5)

NAME
       nullfs -- null file system

SYNOPSIS
       To enable support for this driver, place	the following line in the ker-
       nel configuration file:

	     options NULLFS

       Alternatively,  to  load	the driver as a	module at boot time, place the
       following line in loader.conf(5):

	     nullfs_load="YES"

DESCRIPTION
       The nullfs driver will permit the FreeBSD kernel	to  mount  a  loopback
       file system sub-tree.

EXAMPLES
       To mount	a nullfs file system:

	     mount_nullfs /usr/ports /home/devel/ports

       It  is  also possible to	define an entry	in fstab(5) that looks similar
       to:

       /usr/ports      /home/devel/ports       nullfs	       rw      0       0

SEE ALSO
       fstab(5), mount_nullfs(8)

HISTORY
       The nullfs layer	first appeared in 4.4BSD.

AUTHORS
       The nullfs kernel implementation	was written by John Heideman.

       This manual page	was written by Daniel Gerzo <danger@FreeBSD.org>.
