This is more of a feature for copr as you are exploding out the amount of storage that the distribution uses by each of these architectures. [And if one package wants cpu specialization, then many packages will want it even if it doesn't make sense because the optimized cpu instruction speed is completley lost in anything that asks for memory or disk. > Best regards > > [1]: > https://build.opensuse.org/package/show/home:darix:darktable:master/darktable > _______________________________________________ > devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx > To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx -- Stephen J Smoogen. _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx
