shared storage.conf location for rootless podman

[hmoffatt]

I'd like to configure storage.conf for all users to use with rootless podman. Is there a default storage.conf location that is used if $HOME/.config/containers/storage.conf doesn't exist?

I tried to modify /etc/containers/storage.conf but changes there (specifically additionalimagestores ) don't seem to be used when running rootless.

/usr/share/containers/storage.conf is read I think, but that belongs to the package system and changes would be lost on package upgrade.

I independently noticed this yesterday. It works if you do env CONTAINERS_STORAGE_CONF=/etc/containers/storage.conf. I haven't taken the time to track down why, but if you have the inclination, I would encourage you to file that as a bug.

I figured it wasn't reading /etc/containers/storage.conf at all, but strace shows it is.
