With the proviso that "ignoring/fudging" a SONAME change to avoid this step is an RC bug. A SONAME change going through NEW which doesn't include symbol versioning should be a reject. The work to generate the symbols has already been done but needs a new maintainer (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=543640). That would need to be fixed first. > I know this is a ton of work for a lot > of edge packages where the upstream maintainers are building shared > libraries without really understanding how they work, but it's so > hard to properly manage library upgrades without symbol versioning. Yet these are precisely the packages (and upstreams) which are most in need of such a requirement. -- Neil Williams ============= http://www.linux.codehelp.co.uk/
