Might be that you really don’t need VMs but just lightweight namespace containers. If so, you can use docker/podman, systemd-nspawn or various other tools. The overhead will be less than 1% if you stay within the same architecture as your host.

Wayland is not experimental.

I’ve been trying to sell mine. Went down to 60% of the original price and no takers.

Don’t take funny-colored borders or funny keyboards unless you’re 120% sure you don’t want to sell it in half a year.

I have investigated the idea and came to the conclusion that immutable distros are essentially a research project. They attempt to advance the state-of-art a slight bit but the cost is currently too great.

Perhaps somebody will some day create something that’s worth switching to. But I don’t think that has happened yet, or is happening with any of the current distros. Silverblue might become that with enough polish, but I feel that to get that amount of polish, they would have to make Silverblue the 1st class citizen, i.e. the default install of Fedora.
