Kadlčík: Copr Modularity, the End of an Era

Jakub Kadlčík announced
on his blog that Fedora's Copr build system will
be dropping support for building modules
(groups of RPM packages that are built, installed, and shipped
together) soon:

The Fedora Modularity project never really took off, and building
modules in Copr even less so. We've had only 14 builds in the last two
years. It's not feasible to maintain the code for so few
users. Modularity has also been retired
since Fedora 39 and will die with RHEL 9.

Modularity features in Copr are now deprecated, and it will not be
possible to submit new module builds after April 2025. LWN covered some of the
problems with Fedora's modularity initiative in 2019.
