  2. .SH NAME
  3. venti.conf \- a venti configuration file
  4. .SH DESCRIPTION
  5. A venti configuration file enumerates the various index sections and
  6. arenas that constitute a venti system.
  7. The components are indicated by the name of the file, typically
  8. a disk partition, in which they reside. The configuration
  9. file is the only location that file names are used. Internally,
  10. venti uses the names assigned when the components were formatted
  11. with
  12. .I fmtarenas
  13. or
  14. .I fmtisect
  15. (see
  16. .IR venti-fmt (8)).
  17. In particular, by changing the configuration a
  18. component can be copied to a different file.
  19. .PP
  20. The configuration file consists of lines in the form described below.
  21. Lines starting with
  22. .B #
  23. are comments.
