PAQFS(4)                   Kernel Interfaces Manual                   PAQFS(4)



NAME
       paqfs  - compressed read-only file system

SYNOPSIS
       paqfs  [ -disv ] [ -c cachesize ] [ -m mtpt ] [ -M mesgsize ] [ -S srv‐
       name ] paqfile

DESCRIPTION
       Paqfs interprets the compressed read-only file system  created  by  mk‐
       paqfs(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 sys‐
       tem  for  a  small  persistent storage device, such as a flash ROM.  It
       does not authenticate its clients and assumes each group has  a  single
       member with the same name.

       Options to paqfs are:

       -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 con‐
              sist of a paq file system concatenated with additional data.
