-# 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".
+# See package/makedevs/README for details
#
-# 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.
-
-# Have fun
-# -Erik Andersen <andersen@codepoet.org>
+# This device table is used to assign proper ownership and permissions
+# on various files. It doesn't create any device file, as it is used
+# in both static device configurations (where /dev/ is static) and in
+# dynamic configurations (where devtmpfs, mdev or udev are used).
