%description
Firecracker is an open source virtualization technology that is purpose-built
for creating and managing secure, multi-tenant container and function-based
services that provide serverless operational models.  Firecracker runs
workloads in lightweight virtual machines, called microVMs, which combine the
security and isolation properties provided by hardware virtualization
technology with the speed and flexibility of containers.
%{!?with_jailer:
This package does not include all of the security features of an official
release.  It is not production ready without additional sandboxing.}
