32vfs, cpiofs, tapfs, tarfs, tpfs, v6fs, v10fs, zipfs - mount archival
fs/32vfs [ -b blocksize ] [ -m mountpoint ] [ -p passwd ] [ -g group ]
These commands interpret data from traditional tape or file system for‐
mats stored in file, and mount their contents (read-only) into a Plan 9
file system. The optional -p and -g flags specify Unix-format password
(respectively group) files that give the mapping between the numeric
user- and group-ID numbers on the media and the strings reported by
Plan 9 status inquiries. The -m flag introduces the name at which the
new file system should be attached; the default is /n/tapefs.
32vfs interprets raw disk images of 32V systems, which are ca. 1978
research Unix systems for the VAX (512 byte block size, the default),
and also pre-FFS Berkeley VAX systems (1KB block size).
Cpiofs interprets cpio tape images (constructed with cpio's c flag).
Tarfs interprets tar tape images.
Tpfs interprets tp tapes from the Fifth through Seventh Edition
research Unix systems.
Tapfs interprets tap tapes from the pre-Fifth Edition era.
V6fs interprets disk images from the Fifth and Sixth edition research
Unix systems (512B block size).
V10fs interprets disk images from the Tenth Edition research Unix sys‐
tems (4KB block size).
Zipfs interprets zip archives (see gzip(1)).
These commands are constructed in a highly stereotyped way using the
files fs.c and util.c in /sys/src/cmd/tapefs, which in turn derive sub‐
stantially from ramfs(4).
