I find myself repeating this reply over and over again in various places... The feedback that we (Red Hat) got about SCLs that was filtered down to Engineering was this: 1) Customers really like having the option to install the version of software that their applications needs from a trusted source (the OS vendor/distributor) 2) Customers really *dislike* needing to modify their software to understand the SCL enablement process. 3) Customers very rarely need to install different versions of the same software on the same system. They use containers or VMs for separate applications. So with Modularity, we opted to drop the parallel-installability requirement in favor of parallel-*availability* and the ability to keep the packages installing in the standard locations (/usr/bin, /usr/lib64, etc.) This *is* a net improvement for the vast majority of deployments. _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org
