In a matter of fact, it supports several different modes of work. The default one is to download a tarball. If you use: $ ./build.sh --main-git it will download a copy of the main tree, and compile using it as a reference. Yet, bisecting is not trivial. You'll need to run git bisect under the subdir where the tree was copied. Also, the compilation may fail, due to the backport patches, that won't be synchronized, especially if you're using an old Kernel that requires lots of backport patches to compile/work, as the backport patches always consider the very latest version of the media_tree. If you want to bisect, it is likely easier to clone the media_tree and bisect on it directly. > > Can I simply change the name of the link for the bz2-package in > linux/Makefile?
