NixOS Recovery

Usually if you screw up the configuration.nix you can rollback to a previous generation during boot.

Then you use https://nixos.org/nixos/manual/#sec-rollback to fix the rollback generation.

However if you really screw it up, and none of the generations work, you may need use a recovery method.

Get a NixOS ISO (it's best to get one that has a same or similar version as your current one).

Useful LXD commands

Summarized from https://stgraber.org/2016/03/19/lxd-2-0-your-first-lxd-container-312/.

Interestingly, the LXD command line client is named.... lxc!

List available containers

lxc image list ubuntu:        # ubuntu: is officially supported image source
lxc image list images:        # images: is an unsupported source
lxc image alias list images:  # lists user-friendly names
