SH DESCRIPTION
These commands interpret data from traditional tape or file system formats
stored in
IR file ,
and mount their contents (read-only) into a Plan 9 file system.
The optional
B -p
and
B -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
B -m
flag introduces the name at which the new file system should be
attached; the default is
BR /n/tapefs .
PP

B cpio
tape images (constructed with
BI cpio 's
B c

SH SOURCE
PP
These commands are constructed in a highly stereotyped
way using the files
I fs.c
and
I util.c
in
BR /sys/src/cmd/tapefs ,
which in
turn derive substantially from
IR ramfs (4).
