++# 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 mkcramfs.  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.

+# 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.

+#> connections which carry long term conversations.  For the purpose of
+#> providing services to unknown callers, a service contact port is
+#> defined.  This list specifies the port used by the server process as its

++Description: ext2 filesystem generator for embedded systems
++ `genext2fs' is meant to generate 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.
++ .
++ Warning ! `genext2fs' has been designed for embedded
++ systems. As such, it will generate a filesystem for single-user
++ usage: all files/directories/etc... will belong to UID/GID 0

++# 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.

++
++.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
