Flatcar Container Linux Setup Under Incus on Debian

In case you missed it, Canonical relicensed LXD under AGPLv3 in December 2023 with a mandatory CLA. The LXD project was hard forked as Incus and licensed under an Apache 2.0 License.

Incus is maintained by the same team of developers that first created LXD and is recommended for new users going forward.

OpenWrt 23.05.x Setup Under LXD 5.x on Debian 12 with PCI Passthrough

In case you missed it, Canonical relicensed LXD under AGPLv3 in December 2023 with a mandatory CLA. The LXD project was hard forked as Incus and licensed under an Apache 2.0 License.

Incus is maintained by the same team of developers that first created LXD and is recommended for new users going forward.

If you continue with this guide using Incus, substitute incus for lxc in each command.

Install `lxd` via `snap` and configure

💡 If using Debian 12 (Bookworm) or newer, you can just apt install lxd but keep in mind this pacakge is EOL and new users are encouraged to move to Incus.

Copy that token you just created. Go back to dashboard, click on the domain you want to use
bottom right corner copy the zone id.
