NixOS does provide /etc/protocols and /etc/services. However in our Hydra buildfarm we usually build in a chroot environment where these files are not available. In general that is a good idea as it makes sure there are no hidden dependencies. Obviously sometimes you'll run into problems like we experienced now, which is a pity. However I have adapted the build expression to make it build outside chroot which has solved the problem. Thanks for the quick response. greetings, Rob -- Rob Vermaas [email] rob.verm...@gmail.com
