Ahh, that does sound like a nifty feature! I didn't mean to so strongly imply HAMMER was a knock-off ZFS, more that it fills a similar niche, similar enough that ZFS's dominance kind of takes away from the "wow factor" of HAMMER.

It makes more sense (to me anyway) when you consider that at the time HAMMER was first released, the Linux port of ZFS had only just begun, and FreeBSD had just released their first port of ZFS. Btrfs was also still an out-of-tree patch then, only mainlined in 2009. (not to mention ZFS as a whole probably seemed much more shaky around 2010 with Sun's death-by-Oracle and OpenSolaris getting butchered)

I think back then, having a clean and functional "recreation" of ZFS with all the design bloat removed seemed really promising. Now, it's just a nice FS competing with other nice FSes, except with the downside of being on an "exotic OS". Shame :(
