  26. .SH DESCRIPTION
  27. .I Vacfs
  28. interprets the file system created by
  29. .IR vac (1)
  30. so that it can be mounted into a Plan 9 file hierarchy.
  31. The data for the file system is stored on
  32. .IR venti (8)
  33. with a root fingerprint specified in
  34. .IR vacfile .
  35. .I Vacfs
  36. is currently rather limited: access is read-only,
  37. clients are not authenticated, and groups are assumed to
  38. contain a single member with the same name.
  39. These restrictions should eventually be removed.
