It looks like there are actually two bugs:

- install(1) does check for EOPNOTSUPP, while ZFS seems to return
  EINVAL. This is probably a ZFS bug.
- Inside jails, (un)setting schg is not permitted and returns EPERM. We
  should change the VFS to return EOPNOTSUPP or install(1) to allow
  EPERM as well.

It's a bit late, but I think it would be nice to have this fixed before
8.0.
