If I may ask (and sorry for my ignorance, but): what problem does this workaround solve?
Isn't the whole problem with ZFS loaders the license, and because of the licence, that a ZFS-capable loader isn't built by default?
In other words: Why not use LOADER_ZFS_SUPPORT as long as you have to choose between setting an option or using a patch? Neither works out of the box, so you might as well pick the solution that already exists, no patching involved.
I can only assume I'm missing something vital. :)
(Please note: Makefiles aren't my strongest suite; I tried to figure the answer out by reading the patch, but couldn't. I wrote my first own Makefile, ~15 lines, this weekend.)
