Request: ZFS + tools

[CentralWare]

FreeNAS is BSD, aka BSD licensed. There is no conflict between BSD and CDDL.

FreeNAS WAS BSD.
FreeNAS = TrueNAS
TrueNAS CORE is still mostly Berkley from what I've read (though I see the words Linux Hybrid from time to time) I have not yet personally looked deeper.
TrueNAS SCALE = Debian = Linux = Linus = GPL2 as of October 2020, public release being around February 2022 and still ships with zfs.ko and the likes.
TrueNAS ENTERPRISE...  can't say, I'm not a paying participant for hardware I can get much cheaper elsewhere.

Sorry to intrude
I have to add some more spices to curry.
i slap in the block size.

You can now order two diffrent "blocksizes" 512 and the new one 4096, to gain some more performance.

@patrikg: You're never an intrusion!
Thanks for the update; I'll add it to my documentation.

Interesting claim from a forum Admin at TrueNAS regarding the Oracle/Linux Licensing conflict and how they can distribute Linux + ZFS together without a care:

Given that there have been exactly zero legal moves of any kind, and given the lack of a consistent legal theory, and given Oracle's otherwise non-existent hesitance to use legal action, it is abundantly clear that licensing concerns are merely a façade for Not Invented Here syndrome.

CON: ZRAID "costs" about 10-15% more, from what I've seen, than normal RAID5/6 in terms of parity.  This may be adjustable -- I'm still a bit new to it from the "inside."

there's raidz2, raidz3, etc. that's adjustable parity, yes.

draid also looks very fancy, i'm still not sure what to make of it, one possible summary is it's a kind of generalized raidz that has a kind of dynamic parity when you have spare spares.

good material for a modern opera play i suppose.

openzfs.tcz ~8KB plus info/list/etc (the "Builder" script build_zfs)  Run as non-root.
Completely self-contained (retrieves anything it may need online) with no need for AI -- just a pinch of common sense!

Assumes knowledge of ZFS and ZFS related tools (see .info and builder script for details)

Once it builds the binary TCZs, the resulting zfs.tcz comes in at around 53MB with docs and dev separated.
Docs claim some level of dependency on KSH; nothing I've run thus far has shown that necessity.
Kernel sources are required; if you already have 'em compiled, there's a 45+ minute savings!

Tested under v14.x x86_64 only (for the time being) but will be expanded for x86 and piCore/aarch as time permits.
Suggestions and tweaks welcome!
