Introducing IncusOS!

After over a year of work, I’m very excited to announce the general availability of IncusOS, our own immutable OS image designed from the ground up to run Incus!

IncusOS is designed for the modern world, actively relying on both UEFI Secure Boot and TPM 2.0 for boot security and for full disk encryption. It’s a very locked down environment, both for security and for general reliability. There is no local or remote shell, everything must be done through the (authenticated) Incus API.

Under the hood, it’s built on a minimal Debian 13 base, using the Zabbly builds of both the Linux kernel, ZFS and Incus, providing the latest stable versions of all of those. We rely a lot on the systemd tooling to handle image builds (mkosi), application installation (sysext), system updates (sysupdate) and a variety of other things from network configuration to partitioning.

I recorded a demo video of its installation and basic usage both in a virtual machine and on physical hardware:
