Hi guys!
I am currently trying Arch in a VM and I like it a lot. Wanted to try the hardened kernel all the time, but it has the problem of forbidding custom namespaces.
Tbh I dont even know what that is, but on arch, installing bubblewrap-suid fixes the flatpak problem.
I could not find such a package for Podman, which is used as backend (?) in Distrobox.
Is there a way to make Podman, Docker, Distrobox, Toolbox work on linux-hardened?
This is a big requirement for making a Fedora Atomic version using the hardened kernel, which sounds great, as they completely rely on these containers.
If you are running things inside of containers you aren’t helping yourself by disabling unprivileged namespaces, you are actually just running more things as root. Inside the containers they generally block namespaces anyway.
TBH I’ve never heard anything positive about most of what hardened does.
