[Samba] Samba on ZFS

[Patrick Goetz]

I'm about to deploy a Samba fileserver where the underlying filesystem 
on the data partition is ZFS, and someone on the zfsonlinux list got me 
worried that there might be some problems with doing this (e.g. 
particularly when it comes to extended POSIX ACLs, which I use heavily).

This lead me to this page:
https://www.samba.org/samba/docs/current/man-html/vfs_zfsacl.8.html

where I saw this:  "This module follows the posix-acl behaviour and 
hence allows permission stealing via chown."

I have no idea what permission stealing is, and when I tried to google 
it, I just got references to this man page.

Also, this "This module makes use of the smb.conf parameter acl map full 
control = acl map full control. When set to yes ..."

acl map full control = acl map full control ?

Is that a typo?  I would expect to see, for example
acl map full control = yes

or something like this.

Finally, am I going to run into extended ACL issues by Samba sharing ZFS 
datasets?
