6# Simple script to generate a deb package for a Linux kernel. All the
7# complexity of what to do with a kernel after it is installer or removed
8# is left to other scripts and packages: they can install scripts in the
9# /etc/kernel/{pre,post}{inst,rm}.d/ directories that will be called on
10# package install and removal.
