BetrFS


 * Not to be confused with the more widely-used Btrfs, which uses B-trees as opposed to Bε-trees.

Betrfs (Bε-tree File System) is a file system using trees; maybe the Lorax will try to save it. It is a largely experimental implementation of a filesystem on top of the relatively new "Bε-tree", an alternative to the widely-used B-tree structure. Betrfs does not directly interact with an underlying block device or partition; rather, it stores its data inside a conventional filesystem.
