elemental-toolkit

elemental-toolkit is a toolkit to build, ship and maintain cloud-init driven Linux derivatives based on container images with a common featureset – allows container images to be bootable in VMs, baremetals, embedded devices, and much more.
It is designed to reduce the maintenance surface, with a flexible approach to provide upgrades from container registries. It is cloud-init driven and also designed to be adaptive-first, allowing easily to build changes on top.
