While there are less hardcore ways, I have spent a lot of time with qemu
VMs for various purposes. So that's my go to for such things.

On the other hand, I'm considering eventually creating something along
the lines of Qubes, but Devuan based. A less hardcare solution, but
that's coz all the hard work is done already. That'll have to wait
though, got other things to get done before I can start on it.

Search for apt packages with jail in the name, there's a few I think. Or
containers.
