Incus isn’t a completely new project however, it’s a fork of LXD created by Aleksa Sarai.
Aleksa Sarai is most known for his work on runc, umoci and other OpenContainers projects as well as contributions to the Linux kernel.

But in addition to all that, he’s also been the long time packager of LXD in OpenSUSE.
Aleksa created the fork shortly after Canonical’s decision to take LXD away from Linux Containers with the name Incus being introduced immediately following the LXD 5.16 release. This fork was first intended as a personal project, but has since gathered quite a bit of interest both from the community as well as from former LXD contributors.
