Can we be a bit cautious with the defaults here? With FreeBSD we already
have a hard time disabling acl_xattr
during the provisioning to the ZFS-only systems, as NTACLs are expressed
via NFSv4 ACLs instead.

Even worse situation is with the provisioning to the UFS, due theSamba 4.6
"fix" to extattr code, which now rejects
security.* xattrs entirely, breaking provisioning.

In general, I'd love to see NFSv4 ACLs as a first class citizen in Samba,
as defaulting unconditionally vfs_posixacl
complicates ZFS deployments as well.

With regards,
