- chaos kernel only needs half of the old inode-max-readahead patch, so added a new patch just for chaos-2.4.18
- updated series file for chaos-2.4.18
- updated tinderbox info for chaos-2.4.18
- lbuild: removed '-D' option to cvs which was tanking builds on most clusters, cascading check for rpmbuild and rpm as the method to make rpms
