This is a horrible hack to work around issues with Fedora 31, but other distros might need it to, so we'll move it upstream. I do not recommend this functionality for general use, and the manpages and other documentation will reflect this. But for some upgrade cases, it will be the only thing that allows for a working system. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
