Hi all,

while packaging apx (https://github.com/Vanilla-OS/apx) I noticed something funny with distrobox.

distrobox has the following line in the spec:

Requires:       (%{_bindir}/podman or %{_bindir}/docker)

However, on a new Tumbleweed VM or container, installing distrobox does not pull in podman, it pulls in docker.

I would have assumed that the first in the list, i.e. podman, is being installed if neither is already installed.

No, it is not. zypper (or, likely libsolv) just takes the first in alphabetical order.

this behavior changed then. I can remember when I did change streamlink to offer vlc and mpv, I tested that on TW, and it always offered vlc (as it's the first)

...

Is there a way to tell RPM to "favor" podman over docker, if neither is already installed?

Suggests: podman
