   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 installed 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 (or an alternative location
  10 # specified in KDEB_HOOKDIR) that will be called on package install and
  11 # removal.

 168  kernel development, sandboxes, jails, experimentation, and
