I tried to use build profiles for the first time today, and I found out that pbuilder’s --profiles option advertises to support them, so I ran (via a wrapper and cowbuilder) it with --hookdir .h --profiles nocheck --build Projekte/openjdk-8_8u382-ga-2.dsc but the -P option was not passed to dpkg-buildpackage, making the build fail; the B-D were correctly elided though.
