So, these past couple of days I've been reading the ZFS On-Disk Specification, which is not quite up-to-date, but it serves its purpose.
I find it relatively easy to understand, but I got slightly confused regarding the DSL and especially the Fat Zap structure. But I'm sure it'll start to make more sense when I dive into the code (then again, maybe I'll be more confused ;)
Anyway, tomorrow I'll definitely create the main project site, finish reading the spec and if time permits, I'll start importing the code.
Well, that's it for today :)
