  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

  1084. Sun added support for registering RPC services at an IPv6
  1085. address by creating two new versions of the rpcbind protocol
  1086. (RFC 1833).
  1087. This option enables support in the kernel RPC server for
  1088. registering kernel RPC services via version 4 of the rpcbind
  1089. protocol. If you enable this option, you must run a portmapper
  1090. daemon that supports rpcbind protocol version 4.
  1091. Serving NFS over IPv6 from knfsd (the kernel's NFS server)
  1092. requires that you enable this option and use a portmapper that
  1093. supports rpcbind version 4.

  1095. RPC services using only rpcbind version 2). Distributions
  1096. using the legacy Linux portmapper daemon must say N here.

  1136. files and printers over local networks. Saying Y here allows you to

  1138. access them just like any other Unix directory. Currently, this

  1143. Note: if you just want your box to act as an SMB *server* and make
