  28. Balanced trees are more efficient than traditional file system

  31. large directories and small files. Additional patches are needed
  32. for NFS and quotas, please see <http://www.namesys.com/> for links.
  33. It is more easily extended to have features currently found in
  34. database and keyword search systems than block allocation based file
  35. systems are. The next version will be so extended, and will support
  36. plugins consistent with our motto ``It takes more than a license to

  1057. Solaris NFS servers support an auxiliary NFSv3 ACL protocol that
  1058. never became an official part of the NFS version 3 protocol.
  1059. This protocol extension allows applications on NFS clients to
  1060. manipulate POSIX Access Control Lists on files residing on NFS
  1061. servers. NFS servers enforce POSIX ACLs on local files whether
  1062. this protocol is available or not.

  1064. NFSv3 ACL protocol extension allowing NFS clients to manipulate
  1065. POSIX ACLs on files exported by your system's NFS server. NFS
  1066. clients which support the Solaris NFSv3 ACL protocol can then
  1067. access and modify ACLs on your NFS server.
