There's some terrific docs on FFS from Olaf included with the AOS4 default install in the Documentation drawer, but additional details like this are always fun to read through.
Fun to read, but as ex-commodore employees have said they only developed new standards where existing ones weren't good enough.... Then I think if commodore were still around then they would have switched to btrfs. A 68000 RDB version of btrfs would be awesome.
