-+# 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.
-+

-+.BR genromfs (8),
-+.BR mkisofs (8).
