  9. Choose Y here if you want to access files residing on other
  10. computers using Sun's Network File System protocol. To compile
  11. this file system support as a module, choose M here: the module
  12. will be called nfs.
  13. To mount file systems exported by NFS servers, you also need to
  14. install the user space mount.nfs command which can be found in
  15. the Linux nfs-utils package, available from http://linux-nfs.org/.
  16. Information about using the mount command is available in the
  17. mount(8) man page. More detail about the Linux NFS client
  18. implementation is available via the nfs(5) man page.
  19. Below you can choose which versions of the NFS protocol are
  20. available in the kernel to mount NFS servers. Support for NFS
  21. version 2 (RFC 1094) is always available when NFS_FS is selected.
  22. To configure a system which mounts its root file system via NFS
  23. at boot time, say Y here, select "Kernel level IP
  24. autoconfiguration" in the NETWORK menu, and select "Root file
  25. system on NFS" below. You cannot compile this file system as a
  26. module in this case.
  27. If unsure, say N.

  31. help
  32. This option enables support for version 3 of the NFS protocol
  33. (RFC 1813) in the kernel's NFS client.
  34. If unsure, say Y.
  35. config NFS_V3_ACL
  36. bool "NFS client support for the NFSv3 ACL protocol extension"
  37. depends on NFS_V3
  38. help
  39. Some NFS servers support an auxiliary NFSv3 ACL protocol that
  40. Sun added to Solaris but never became an official part of the
  41. NFS version 3 protocol. This protocol extension allows
  42. applications on NFS clients to manipulate POSIX Access Control
  43. Lists on files residing on NFS servers. NFS servers enforce
  44. ACLs on local files whether this protocol is available or not.
  45. Choose Y here if your NFS server supports the Solaris NFSv3 ACL
  46. protocol extension and you want your NFS client to allow
  47. applications to access and modify ACLs on files on the server.
  48. Most NFS servers don't support the Solaris NFSv3 ACL protocol
  49. extension. You can choose N here or specify the "noacl" mount
  50. option to prevent your NFS client from trying to use the NFSv3
  51. ACL protocol.
  52. If unsure, say N.

  57. help
  58. This option enables support for version 4 of the NFS protocol
  59. (RFC 3530) in the kernel's NFS client.
  60. To mount NFS servers using NFSv4, you also need to install user
  61. space programs which can be found in the Linux nfs-utils package,
  62. available from http://linux-nfs.org/.
  63. If unsure, say Y.

  77. help
  78. If you want your system to mount its root file system via NFS,
  79. choose Y here. This is common practice for managing systems
  80. without local permanent storage. For details, read
  81. <file:Documentation/filesystems/nfs/nfsroot.txt>.
  82. Most people say N here.

  93. The kernel now provides a method for translating a host name into an

  107. Say Y here if you want NFS to use the new idmapper upcall functions.
  108. You will need /sbin/request-key (usually provided by the keyutils
  109. package). For details, read
