# buildforkernels macro hint: when you build a new version or a new release
# that contains bugfixes or other improvements then you must disable the
# "buildforkernels newest" macro for just that build; immediately after
# queuing that build enable the macro again for subsequent builds; that way
# a new akmod package will only get build when a new one is actually needed
