Bug ID: 284670
Summary: Handbook fails to list limitations of `zfs allow
mount`
Product: Documentation
Version: Latest
Hardware: Any

Even after delegating `mount` along with `recv` and `create`, an unprivileged
user can't mount a ZFS file system unless at least
- `vfs.usermount` is set to 1
- The user owns the directory onto which the filesystem would be mounted
Using `zfs recv -u ...` does not mitigate this limitation.
>From a practical perspective, `zfs recv` seems as though it would only work in
very limited situations (user owns all mount points, including those of child
filesystems) and only if the security implications of opening up
`vfs.usermount` are acceptable.
