  757. disk. Coda has several advantages over NFS: support for
  758. disconnected operation (e.g. for laptops), read/write server
  759. replication, security model for authentication and encryption,
  760. persistent client caches and write back caching.
  761. If you say Y here, your Linux box will be able to act as a Coda
  762. *client*. You will need user level code as well, both for the
  763. client and server. Servers are currently user level, i.e. they need
  764. no kernel support. Please read
  765. <file:Documentation/filesystems/coda.txt> and check out the Coda
  766. home page <http://www.coda.cs.cmu.edu/>.
  767. To compile the coda client support as a module, choose M here: the
  768. module will be called coda.
