Details:


Recently linux kernel 4.20.5-200.fc29.x86_64 from
https://evilpiepirate.org/git/bcachefs.git
is presently (feb 2019) is compile-able and use-able.
Their aim is to eventually mainstream the feature and integrate it directly
into the kernel, so that kernel can reside on the filesystem and avoid needing
to load an external kernel-module.
Kernel feature is presently not enterprise ready. 
Bcachefs is also designed to be a successor to ext4 as well as an alternative
to btrfs/ZFS eleviating their short comings.  

grub2 may need to be able to  
* boot kernels bcachefs (temporary workaround is to use a ext4 boot partition)

* traverse and search the file-system to locate image-files etc. 

Filing this anticipatory feature tracking bug, so as to 
* keep track of bcachefs support in grub2
