-.Dt NANDFS 5
-.Os
-.Sh NAME
-.Nm nandfs
-.Nd NAND Flash file system
-.Sh SYNOPSIS
-To compile support for the
-.Nm ,
-place the following in your kernel configuration file:
-.Bd -ragged -offset indent
-.Cd "options NANDFS"
-.Ed
-.Pp
-Even though the NAND FS can be used with any storage media, it has been
-optimized and designed towards NAND Flash devices, so typically the following
-driver is used:
-.Bd -ragged -offset indent
-.Cd "device nand"
-.Ed
-.Sh DESCRIPTION
-The
-.Nm
-driver enables
-.Fx
-with support for NAND-oriented file system.
-.Pp
-It is a log-structured style file system with the following major features and
-characteristics:
-.Bl -bullet
-.It
-Hard links, symbolic links support
-.It
-Block journaling
-.It
-Copy-On-Write
-.It
-Snapshots (continuous, taken automatically, simultaneously mountable)
-.It
-Quick crash recovery at mount time
-.It
-64-bit data structures; supports many files, large files and volumes
-.It
-POSIX file permissions
-.It
-Checksum / ECC
-.El
-.Sh EXAMPLES
-The most common usage is mounting the file system:
-.Pp
-.Dl "mount -t nandfs /dev/<gnandN> /mnt"
-.Pp
-or:
-.Dl "mount_nandfs /dev/<gnandN> /mnt"
-.Pp
-where
-.Ar gnandN
-is the GEOM device representing a Flash partition (slice) containing the
-.Nm
-structure, and
-.Pa /mnt
-is a mount point.
-.Pp
-It is possible to define an entry in
-.Pa /etc/fstab
-for the
-.Nm :
-.Bd -literal
-/dev/gnand0 /flash nandfs rw 0 0
-.Ed
-.Pp
-This will mount a
-.Nm
-partition at the specified mount point during system boot.

-.Xr gnand 4 ,
-.Xr nand 4 ,
-.Xr mount_nandfs 8 ,
-.Xr nandfs 8 ,
-.Xr nandsim 8 ,
-.Xr nandtool 8 ,
-.Xr umount_nandfs 8
-.Sh HISTORY
-The NAND FS concepts are based on NILFS principles and initial implementation
-was derived from early read-only NILFS NetBSD code.
-Since then the NAND FS
-code diverged significantly and is by no means compatible with NILFS.
-.Pp
-The NAND Flash file system first appeared in
-.Fx 10.0 .
-.Sh AUTHORS
-.An -nosplit
-The NAND FS was written by
-.An Grzegorz Bernacki
-with the help of
-.An Mateusz Guzik ,
-based on the NetBSD code created by
-.An Reinoud Zandijk .
-Additional help and support by
-.An Lukasz Plachno ,
-.An Jan Sieka
-and
-.An Lukasz Wojcik .
