  1. U9fs is a program that serves Unix files to Plan 9 machines using the 9P
  2. protocol. Its standard input and output are connected to a network
  3. connection, typically TCP on an Ethernet. It assumes Plan 9 uids match
  4. Unix login names, and changes to the corresponding Unix effective uid
  5. when processing requests. Characters in file and directory names
  6. unacceptable to Plan 9 are translated into a three-character sequence:
  7. followed by two hexadecimal digits. U9fs serves both 9P1 (the 9P
  8. protocol as used by the second and third editions of Plan 9) and 9P2000.
