# 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. |

User-mode Linux is a port of the Linux kernel to its own system call |

interface. It provides a kind of virtual machine, which runs Linux |

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

many other things. |
