ZTS: acl/off/posixmode never passes? #16030

I would like help debugging why I'm unable to make acl/off/posixmode pass when running ZTS locally.

It seems that on my setup for some reason g=--- disallows staff2, but I don't understand what's going on or why this would pass on other systems but not Fedora (SELinux? Something different about tmpfs in Linux 6.6?)
