Failing on various distros (VM: openSUSE Tumbleweed, Debian stable and testing,
Centos 7; also on real HW openSUSE), fs: ext4, xfs, btrfs, vfat.

I wonder, what I do wrong. I posted whole output of one machine below.

I thought that for some cases it'd be nice, if .needs_root = 1 was added
internally. But probably bad idea, I guess we should be explicit and add it.

Kind regards,
Petr
