NAME
paqfs - compressed read-only file system
SYNOPSIS
paqfs [ -adipqsv ] [ -c cachesize ] [ -m mtpt ] [ -M
mesgsize ] [ -S srvname ] paqfile
DESCRIPTION
Paqfs interprets the compressed read-only file system cre-
ated by mkpaqfs(8) and stored in paqfile so that it can be
mounted into a Plan 9 file system. Paqfs is typically used
to create a stand alone file system for a small persistent
storage device, such as a flash ROM. It does not authenti-
cate its clients and assumes each group has a single member
with the same name.
Options to paqfs are:
-a Treat everyone as group/owner.
-c cachesize
The number of file system blocks to cache in memory.
The default is 20 blocks.
-M mesgsize
The maximum 9P message size. The default is sufficient
for 8K byte read message.
-d Output various debugging information to stderr.
-i Use file descriptors 0 and 1 as the 9P communication
channel rather than create a pipe.
-q Suppress the output of the archive creation date and
fingerprint to stderr.
-m mtpt
The location to mount the file system. The default is
/n/paq.
-s Post the 9P channel on #s/srvname, default #s/paqfs,
rather than mounting it on mtpt.
-S The name to post in #s. The default is paqfs.
-p Both post the 9P channel in #s and mount the paqfile in
to the filesystem.
-v Verify the integrity of the paqfile. Before mounting
the file system, the entire file is parsed and the sha1

checksum of the file system data is compared to the
checksum embedded in the file. This option enables the
use of paqfs with files that consist of a paq file sys-
tem concatenated with additional data.
