# 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

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