In some situations rootless works better, e.g. I was not able to use podman with sudo in a container that had `ping` in it [1]. OTOH rootless uses `fuse-overlayfs` instead of the in-kernel overlay2 driver, and initially I ran into a few bugs since it is not yet a fully POSIX filesystem (much like how the initial overlay kernel driver was buggy , and it wasn't only until overlay2 when it started working reliably with docker). Having said that I've been using only podman as an experiment at home, and upstream is very responsive in fixing bugs. There is also a `vfs` backend that can be used as a fallback until bugs in fuse-overlays get fixed.

Would be nice if someone developed a testsuite that exercises all the usual FS operations that a container uses (permissions, setuid, setcap, symlinks, etc.) and compares vfs vs fuse-overlayfs vs in-kernel overlayfs vs docker?
