I didn't initially, I do now. Like I said, I haven't been following that one 100%. I know it isn't block-clone per say, so much as some underlying problem it pokes with a pointy stick. Small chance multiplied by a bunch of ZFS IOPS. Seems like I'd have to revert it all the way back to fresh install if I want to get rid of all potential corruption unrelated to sysctl panic. But I'll do myh busy-work cycle (*) with that one and maybe another with it off and see what happens. * full kernel+world, plus my local poudriere package build, currenly wedged a bit with the heimdall build issue.
