virtme-ng-init is an extremely lightweight init process for virtme-ng [1] implemented in Rust.
Its primary goal is to speed up the boot time of virtme-ng instances.
virtme-ng-init is able to perform any necessary initialization in the virtualized environment, such as mounting filesystems, starting essential services, and configuring the system before handing over control to the main user-space processes (typicall a shell session).
