sys-kernel/vanilla-kernel: New package providing built kernel
New package whose primary purpose is to provide a zero-effort way of
ensuring that your system is running a working distribution kernel that
gets cleanly upgraded as part of @world upgrades. The secondary goal
is to make it possible to build universal binary packages that can be
afterwards installed on variety of systems with different hardware,
/boot layouts and bootloaders.
