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.

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