Description of problem: kernel package is built with "CONFIG_NILFS2_FS is not set". It should be provided as "m", a kernel module because Fedora provides nilfs-utils package. It is inconsistent.
Fedora also provides media players that can't play 90% of the media that people release. There's no consistency requirement when building packages in Fedora, oddly enough. Anyway, we can turn this back on in rawhide and move it to the modules-extra subpackage but usage of Nilfs2 in Fedora is likely very low.
Enabled in rawhide. Will be in tomorrow's build.
Thanks. I'd like to try nilfs2.
