ZFS's popularity is growing, and not including it by default is a
bit frustrating. On top of that, the base iso includes ZFS
anyway due to other packages depending upon it.

I think we're in the clear to do this on the basis that Oracle
probably doesn't care, it is probably fine (the SFLC agrees) and
we're a small fish. If a copyright holder asks us to, we can
definitely revert it again.

This reverts commit 33d07c7.

Motivation for this change
Things done
  • Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS)
  • Built on platform(s)
    • NixOS
    • macOS
    • other Linux distributions
  • Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nox --run "nox-review wip"
  • Tested execution of all binary files (usually in ./result/bin/)
  • Determined the impact on package closure size (by running nix path-info -S before and after)
  • Assured whether relevant documentation is up to date
  • Fits CONTRIBUTING.md.

ZFS's popularity is growing, and not including it by default is a
bit frustrating. On top of that, the base iso includes ZFS
_anyway_ due to other packages depending upon it.

I think we're in the clear to do this on the basis that Oracle
probably doesn't care, it is probably fine (the SFLC agrees) and
we're a small fish. If a copyright holder asks us to, we can

zfs cannot be distributed. Disabling it in the isos.
33d07c7 
It seems that it is a GPL violation to distribute zfs in the
installation ISOs.

If anyone knows the issue better and has a reason to reenable it
legally, feel free to reenable it. I don't know much about it.

@armijnhemel says:

"if we ship the ZFS source code, then for all practical purposes the GPL has been fullfilled in my opinion. This also seems to be the opinion of Ubuntu and SFLC."

and we do distribute the source code via binary cache, and the build instructions by virtue of having nixpkgs in the image.

Risks vs. benefits ratio seems very favorable to me.

I believe this is safe for 18.09, too.
