I've been using this on top of both Ububtu and Fedora Silver blue, to run a Fedora toolbox, works nicely.
There is also a host-exec script that allows to spawn commands outside the container while inside. E.g. it is not possible to run 'podman' nested, but with host-exec can still run containers while inside distrobox (distrobox isn't used for isolation, but for the ability to run a mutable OS of your choice).<p>There are a small number of programs, usually those that need root (such as 'cpupower') which also need to be run "outside".
