From @TPG in cooker mailing list:
I’d like to inform you that I was able to format my ssd disk to F2FS file system when installing iso with calamares.
System boots fine, and thanks to patches for grub2 a F2FS partition is recognised and boots fine.
For those who are not familiar with F2FS, this is a file system designed to ssd disks. Now OpenMandriva is the only one distribution that does support F2FS especially inside grub2.
If you want to try it feel free to test this post beta2 iso:
