   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.

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