LGTM, but I thought this very recently changed and may not be needed any more ?

I think it's easier/more straight-forward to change helper_binaries_dir= in containers.conf.

Hmm. Some different tradeoffs there; that would affect the main podman binary too (which is fine) but logically the goal here is to have two podman setups.

So I'm not totally sure it's universally better; to avoid debate I ended up just documenting that in addition too.

CONTAINERS_CONF=/path/to/special.conf podman ... would work without impacting other users/binaries. Or --module /path/to/special.conf.
