We try hard NOT to change the KBI within a single stable branch. we do things like add spare fields before we make a new stable branch to help with this. > In any case, I do strongly recommend the use of PORTS_MODULES in > /etc/src.conf to assure that the kernel modules always get re-built when > the kernel is re-built. so that the sources, the kernel, and the module are > in sync.
