zfs-fuse daemon is not starting on hardened system with PaX enabled. "paxctl -m /usr/sbin/zfs-fuse" solves the issue.
It was mentioned in https://bugs.gentoo.org/show_bug.cgi?id=332395#c2
Closing since zfs-fuse was removed from tree. But adding bug 358697 to Blocks: -line since if the package is reintroduced to tree, this one should get fixed too.
