The contents does not, the sstate checksum however does due to the dependencies. The dependencies are thinks like gtk+ and dbus. > However, if the dependency really doesn't matter, then why isn't ABISAFE > correct > in each case? I'm using ABISAFE in this context as shorthand for SIGGEN_EXCLUDERECIPES_ABISAFE and those are defined as things which don't need to rebuild if the dependency changes. gtk+ and dbus both provide libraries and we do want software to rebuild if they change. In the allarch case we could whitelist the dependency however in the general case we shouldn't. Even with that problem addressed somehow, it leaves an issue with ipk multilibs where the distcc-config allarch recipe would always depend upon "distcc" and hence distcc would get pulled into the image, regardless of any other multilib settings (which in turn pulls in gtk+ for example). A "lib64-xxx-image" would therefore end up with near enough two copies of half the system due to this. This is something we really need to fix in the opkg implementation of multilibs but I have no idea how. Combine the two issues together, neither of which can be addressed at this point of the release cycle and I put the above patch forwards until we can better resolve this.
