Ideally, this would be done by podman, but in the mean time do it in
podman-compose for a better user experience.

If that's the case, do we want the exception to bubble up? Or silently fail? Bubbling up the error might give the user a better idea of what the problem actually is.

Errors like it should be catched and printed to user understand what is wrong.

That's right! This solve the issue!

Updated the PR to only perform this action if in compatibility mode as suggested in #185.

I see that the compatibility mode is not in the principal (devel) branch -- issue #185 was closed but the commit did not introduce the compatibility mode, was the idea scrapped? This PR proposes a commit adding the mode but it's not merged. Sorry for sharing my confusion, but I tripped over the "let's create empty directories for volumes for which source files are missing" behaviour today, as I haven't used Docker and am not used to its behaviour.
