Patch from gtj -- http://bugs.uclibc.org/view.php?id=39
0000039: Adds options to ext2 filesystem creation Adds ability to specify block and inode counts, reserved blocks, permissions squash and device table in the configuration. Also adds capability to gzip output and to copy the resulting image to a secondary location like a tftp server's root directory.
