That "-p" does the trick .. Obviously I was overlooking it, because the short
description looks not interested ..

Anyway, with that option I submitted another fix to use blkid as fallback.

That's to be discussed, and also I'm confused why only "udevadm info" did not
communicate with host daemon (or it does, but somehow host daemon looks for
chroot instead, which is buggy). The child process forked by yast should
inherit the same environment ...
