Subject:    [uClinux-dev] [PATCH] mkdevdir-genromfs.sh: script to make /dev
From:       Mike Frysinger <vapier () gentoo ! org>

The genromfs utility (which is used to generate ROMFS images) is a little
funky when it comes to /dev.  This script will parse a normal device table
and create the funky files that genromfs keys off of.
