jails Linux jail vs linux chroot

[Schroter]

Hi All,
Would anyone know if there is a difference between a linux jail and linux chroot environment.
Thanks & Best Regards

A jail(8) does more than a simple filesystem separation (chroot(8)). Jails run their processes in an entirely different namespace inside the kernel. Chroot'ed processes do not.

podman or docker work in a bhyve vm
but not in a jail or chroot

podman works

sudo apt install podman podman-compose

podman run quay.io/podman/hello

Just to make sure you understand: normally the Linuxulator uses neither a chroot nor a jail. It uses a fallthrough filesystem, falling through to the real filesystem after /compat/linux.

So there are really 4 ways to run Linux binaries:
- Linuxulator filesystem fallthough
- chroot
- jail
- vm
