[opensuse-packaging] Differencies between tools?

I've been thinking a little.. What's the differencies between building packages with y2pmbuild and build? I'd like the best of the worlds.. I'd like to build several architectures in one run (build), but I'd also like to have the packages signed and dumped to the repositary I'm building. One problem is that it appears as the rpm's doesn't get signed.. I have to dig into that a bit more, I'm setting some traps in the y2pmbuild script to see if I can find something out.. I guess a script running 'y2pmbuild-10.1' and then 'linux32 y2pmbuild' would do the trick, but I'd like to know which exit codes y2pmbuild generates for failure and success. -- Anders Norrbring Norrbring Consulting
