+# 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.
