 #
 # Simple script to generate a deb package for a Linux kernel. All the
 # complexity of what to do with a kernel after it is installed or removed
 # is left to other scripts and packages: they can install scripts in the
 # /etc/kernel/{pre,post}{inst,rm}.d/ directories (or an alternative location
 # specified in KDEB_HOOKDIR) that will be called on package install and
 # removal.

	as a user process under another Linux kernel. This is useful for
	kernel development, sandboxes, jails, experimentation, and
	many other things.
