I'll get right to the point. I've only found one issue so far, and it's to do with the installation: if one installs this with separate /boot and /boot/efi partitions (which I did and is kind of needed with a f2fs root partition), then grub won't install, it'll /say/ it installed correctly. But upon booting it's not there and further inspection the ESP partition is completely void of any files.
I figured that might be something that should be reported.
This is in the current KDE build.
