Hi, Thanks to "crazy" our kmod now supports Zstd compressed kernel modules. This means kernel-release-clang modules are no more compressed with xz in favour of zstd. Switching to that compression gives benefits of faster boot.
On my tests I noticed boot improvements from 10 to 7 seconds on my ssd disk. https://github.com/OpenMandrivaAssociation/kmod/blob/master/zstd-support.patch
