So it finally went through and i found some errors in my package. Mainly precision problems with the unit tests on i386.

However there were also some errors not related to this. For example:

zsh» nd_build nd+debian sid i386 psignifit_3.0\~beta.20120503.1-1.dsc
Building for nd+debian sid i386 ...

It would seem like the call to:

forking: cp -al /home/haenel/nd_cowbuildroot/cow/nd+debian-sid-i386.cow /home/haenel/nd_cowbuildroot/build/cow.22381

perhaps failed?
