In their own words
AuroraBoot
AuroraBoot is Kairos’s bootstrapper for creating machine images, provisioning systems, and managing fleets. It builds ISO, UKI, raw disk, and system-extension images from Kairos flavors or container images, then supports provisioning by PXE/netboot, Redfish, or USB. Its fleet server pairs a browser dashboard for artifact building, deployment, and node management with a REST API and Go client; API documentation is available through Swagger UI at /api/docs. Registered nodes can receive upgrades, reboots, resets, cloud-config, and shell commands, with command output captured. The guided Artifact Builder offers templates for Ubuntu, Fedora, Debian, openSUSE, Alpine, Rocky, and Hadron. A SecureBoot key store handles PK, KEK, db, and TPM PCR policy keys, with signed export and import. Documented architectures are amd64, arm64, and riscv64. The self-hosted software is free under Apache License 2.0; its fleet server uses SQLite by default and can use PostgreSQL. Docker or a container engine is required. One security consideration: netboot serves files over unauthenticated plain HTTP to reachable clients.
