I'll do another compile run today and see if things work out.
Any further things somebody needs in the kernel? I am very willing to share the packages once omvextras is working correctly again! In case people want to try btrfs raid56 or other new features like the ext4 encryption (already compiled in), etc. Currently, the most vital FSes are compiled into the kernel, the remaining ones are are modules. I also can include more device drivers as modules for convinience.
