  32. .SH DESCRIPTION
  33. These commands interpret data from traditional tape or file system formats
  34. stored in
  35. .IR file ,
  36. and mount their contents (read-only) into a Plan 9 file system.
  37. The optional
  38. .B -p
  39. and
  40. .B -g
  41. flags specify Unix-format password (respectively group) files
  42. that give the mapping between the numeric user- and group-ID
  43. numbers on the media and the strings reported by Plan 9 status
  44. inquiries.
  45. The
  46. .B -m
  47. flag introduces the name at which the new file system should be
  48. attached; the default is
  49. .BR /n/tapefs .
  50. .PP
  51. .I 32vfs
  52. interprets raw disk images of 32V systems, which are ca. 1978 research Unix systems for
  53. the VAX, and also pre-FFS Berkeley VAX systems (1KB block size).
  54. .PP
  55. .I Cpiofs
  56. interprets
  57. .B cpio
  58. tape images (constructed with
  59. .BI cpio 's
  60. .B c
  61. flag).
  62. .PP
  63. .I Tarfs
  64. interprets
  65. .I tar
  66. tape images.
  67. .PP
  68. .I Tpfs
  69. interprets
  70. .I tp
  71. tapes from the Fifth through Seventh Edition research Unix systems.
  72. .PP
  73. .I Tapfs
  74. interprets
  75. .I tap
  76. tapes from the pre-Fifth Edition era.
  77. .PP
  78. .I V6fs
  79. interprets disk images from the
  80. Fifth and Sixth edition research Unix systems (512B block size).
  81. .PP
  82. .I V10fs
  83. interprets disk images from the
  84. Tenth Edition research Unix systems (4KB block size).

  87. These commands are constructed in a highly stereotyped
  88. way using the files
  89. .I fs.c
  90. and
  91. .I util.c
  92. in
  93. .BR /sys/src/cmd/tapefs ,
  94. which in
  95. turn derive substantially from
  96. .IR ramfs (4).
