Yes. I'm using dpkg 1.19.0.4, which knows "Rules-Requires-Root: no", but does
not know --rules-requires-root (added in 1.19.1). export
DEB_RULES_REQUIRES_ROOT=no fixes the problem for my version (but that does not
break the build). I just wanted to save time for the others, but 1) there are
probably not many people using OBS to build Debian packages and 2) maybe it's
just me who does not know it.
It looks to me debhelper is not used for kernel Debian packaing, right?
At least building works even I don't have it.
As a result of this I'll also update openSUSE dpkg package to latest release.
Thanks all for explanation.
Kind regards,
Petr
