Isn't Incus/LXD separate from and running on top of LXC?
People sometimes seem to use the names interchangeably which can be annoying because I run just plain LXC but when looking stuff up and come across "this is how you do XYZ on LXC" they are actually talking about LXD and it doesn't really apply.
I can't recall what is was last time, but this has happened a couple of times already...
