I am tempted and have started to use ACLs.  Once you&#x27;ve got a ZFS filesystem (in my case, on FreeBSD like the author), you have full NFSv4 ACL support.  If you export that over NFSv4, those ACLs are visible to all client systems.  And if you export it over Samba, they are visible to Windows clients as well.<p>I don&#x27;t think the support here is too awful: given that it&#x27;s what NFSv4 supports, it should be available to all clients.  It doesn&#x27;t help that the tools are crap on the Linux side--the POSIX.1e DRAFT ACLs are all they support last time I checked, and this dead non-standard should really just be replaced by the NFSv4 model at this point.  Not sure what ZFSOnLinux does to work around this shortcoming.
