# This package bundles a customized Linux kernel in a format that can only be
# consumed by libkrun, which will run it in an isolated context using KVM
# Virtualization. This kernel can't be used for booting a physical machine
# and, by being bundled in a dynamic library, it can not be mistaken as a
# regular kernel.
#
# The convenience of distributing a kernel this way and for this purpose was
# discussed here:
