[valentin@nebuchadnezzar libpod]$ podman export 254 -o foo.tar
Error: error creating file "foo.tar": open foo.tar: permission denied

... while redirecting ... > foo.tar works. I assume that's namespace related but we might need to document that in the manpage (and the help message).

do you get any error if you try buildah unshare touch foo.tar from the same directory?

$ buildah unshare
$ podman export ... -o foo.tar

works.

If I do a buildah unshare touch foo.tar and try to export after, outside the namespace, it doesn't work.

rootless: force same cwd when re-execing
a4f7735 
when joining an existing namespace, we were not maintaining the
current working directory, causing commands like export -o to fail
when they weren't referring to absolute paths.

Closes: containers#2381
