OK, sorry, that's not quite fair; we should add details about experience with alternative approaches in nfsd and samba (mapping between ACL models, adding "posix" acl support to the protocols, making the protocol daemon store and enforce the ACL instead of the filesystem). And probably cc: samba-technical on that one message so they can confirm or deny any of that. --b. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
