Not much choice - even community colleges now have to teach students about this ACL model in their sysadmin courses. >> And what would native ACL support mean for Samba? > > RichACLs'll do it, but I feel sorry for the admins :-).

RichACLs will make a more natural mapping for Samba and NFSv4 - and it is far too late to remove the requirement for Windows and MacOS (among other clients) support. -- Thanks, Steve
