Hi, I attempting to rebuild an SRPM from RDO (openstack-ironic) to apply a patch needed for my environment. I was simply trying to do yumdownloader --source openstack-ironic rpm2cpio openstack-ironic-2015.1-dev684.el7.centos.src.rpm | cpio -i # modify spec and apply patch rpmbuild --define '%_srcrpmdir .' --define '%_sourcedir .' -bs openstack-ironic.spec mock openstack-ironic-2015.1-dev684.el7.centos.src.rpm However this gives me a build failure with /var/tmp/rpm-tmp.jyD2vL: line 35: cd: ironic-%{upstream_version}: No such file or directory I had a feeling this was because of the workflow introduced by delorean (something I am not immediately familiar with). I started looking at this page https://www.rdoproject.org/packaging/rdo-packaging.html And followed it through I understand what delorean is, what it's trying to achieve, and how the macros work etc. I was able to fix my build with by adding %{!?upstream_version: %global upstream_version 2015.1.dev684} I'm just wondering if it is possible to tweak the rpm specs that delorean/RDO use to add such a conditional above to all rpms, so that it is possible for us Operators to still rebuild these SRPMS as needed using the tools we always have used. While I can appreciate delorean and everything it does, from a pure operators perspective, we aren't a fan of having to use custom tools to build packages for all different products/infrastructure under our control. If this could be done it would be very much appreciated! Regards, Graeme -- Graeme Gillies Principal Systems Administrator Openstack Infrastructure Red Hat Australia
