Makes sense to me. It could even get sent out to users about as fast as
a new kernel by itself, since they could just add a package dependency
to update the init scripts when the end-user installs the new kernel
package.

Anyone messing with the kernel directly is likely 1) smart enough to
deal with existing FIFO semantics, and 2) able to modify their own init
scripts to get some additional security if they so desire.
