   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.

  93 User-mode Linux is a port of the Linux kernel to its own system call
  94 interface.  It provides a kind of virtual machine, which runs Linux
  95 as a user process under another Linux kernel.  This is useful for
  96 kernel development, sandboxes, jails, experimentation, and
  97 many other things.
