++# When building a target filesystem, it is desirable to not have to
++# become root and then run 'mknod' a thousand times. Using a device
++# table you can create device nodes and directories "on the fly".
++#
++# This is a sample device table file for use with genext2fs. You can
++# do all sorts of interesting things with a device table file. For
++# example, if you want to adjust the permissions on a particular file
++# you can just add an entry like:
++# /sbin/foobar f 2755 0 0 - - - - -
++# and (assuming the file /sbin/foobar exists) it will be made setuid
++# root (regardless of what its permissions are on the host filesystem.
++# Furthermore, you can use a single table entry to create a many device
++# minors. For example, if I wanted to create /dev/hda and /dev/hda[0-15]
++# I could just use the following two table entries:
++# /dev/hda b 640 0 0 3 0 0 0 -
++# /dev/hda b 640 0 0 3 1 1 1 15
++#
++# Device table entries take the form of:
++# <name> <type> <mode> <uid> <gid> <major> <minor> <start> <inc> <count>
++# where name is the file name, type can be one of:
++# f A regular file
++# d Directory
++# c Character special device file
++# b Block special device file
++# p Fifo (named pipe)
++# uid is the user id for the target file, gid is the group id for the
++# target file. The rest of the entries (major, minor, etc) apply only
++# to device special files.

++.SH NAME
++genext2fs \- ext2 filesystem generator for embedded systems
++.SH SYNOPSIS
++.B genext2fs
++.RI [ options ] " image"
++.SH DESCRIPTION
++\fBgenext2fs\fP generates an ext2 filesystem
++as a normal (non-root) user. It doesn't require you to mount
++the image file to copy files on it. It doesn't even require
++you to be the superuser to make device nodes.
++.SH OPTIONS
++.TP
++.BI -x \ image
++Use this image as a starting point
++.TP
++.BI -d \ directory
++Add this directory as source
++.TP
++.BI -f \ FILE
++.TP
++.BI -D \ FILE
++Uses the named FILE as a device table file, to create device
++nodes and directories "on the fly".
++.TP
++.BI -b \ blocks
++Size in blocks
++.TP
++.BI -i \ inodes
++Number of inodes
++.TP
++.BI -r \ reserved
++Number of reserved blocks
++.TP
++.BI -g \ path
++Generate a block map file for this path
++.TP
++.BI -e \ value
++Fill unallocated blocks with value
++.TP
++.BI -z
++Make files with holes
++.TP
++.BI -U
++Squash owners making all files be owned by root
++.TP
++.BI -P
++Squash permissions on all files
++.TP
++.BI -q
++Squash permissions and owners (same as -P -U)
++.TP
++.BI -v
++Print resulting filesystem structure
++.TP
++.BI -h
++Display help
++.TP
++.SH EXAMPLES
++
++.EX
++.B
++ genext2fs -b 1440 -d src /dev/fd0
++.EE
++
++All files in the
++.I src
++directory will be written to
++.B /dev/fd0
++as a new ext2 filesystem image. You can then mount the floppy as
++usual.
++
++.EX
++.B
++ genext2fs -b 1024 -d src -D device_table.txt flashdisk.img
++.EE
++
++This example builds a filesystem from all the files in
++.I src
++, then device nodes are created based on the content the device_table file
++.I dev.txt.
++An example device file follows:
++
++.EX
++ #<name> <type> <mode> <uid> <gid> <major> <minor> <start> <inc> <count>
++ /dev d 755 0 0 - - - - -
++ /dev/mem c 640 0 0 1 1 0 0 -
++ /dev/tty c 666 0 0 5 0 0 0 -
++ /dev/tty c 666 0 0 4 0 0 1 6
++ /dev/loop b 640 0 0 7 0 0 1 2
++ /dev/hda b 640 0 0 3 0 0 0 -
++ /dev/hda b 640 0 0 3 1 1 1 16
++.EE
++
++This device table creates the /dev directory, a character device
++node /dev/mem (major 1, minor 1), it also creates /dev/tty,
++/dev/tty[0-5], /dev/loop[0-1], /dev/hda, and /dev/hda0 to /dev/hda15
++.SH BUGS
++\fBgenext2fs\fP does not support hard links. Hard links present in the input
++tree will be represented as separate files in the ext2 image.
