From b7b56dd8fbe123958e196f396dab5ff3000b68dd Mon Sep 17 00:00:00 2001 From: Patrick Georgi Date: Mon, 14 Sep 2009 13:29:27 +0000 Subject: New cbfstool. Works without mmap or fork/exec and supports fixed location files. Some parts are salvaged from the pre-commit version (esp. stage and payload creation), others are completely rewritten (eg. the main loop that handles file addition) Also adapt newconfig (we don't need cbfs/tools anymore) and fix some minor issues in the cbfstool-README.
