NAME

nullfs —

null file system

SYNOPSIS

To enable support for this driver, place the following line in the kernel 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"

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

To mount a nullfs file system:

mount_nullfs /usr/ports
  /home/devel/ports

The nullfs layer first appeared in 4.4BSD.

The nullfs kernel implementation was written by John Heideman.
