NAME

paqfs  − compressed read-only file system

SYNOPSIS

­paqfs [ ­-disv ] [ ­-c ­cachesize ] [ ­-m ­mtpt ] [ ­-M ­mesgsize ] ­paqfile

DESCRIPTION

­Paqfs interprets the compressed read-only file system created 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 authenticate its clients and assumes each group has a single member with the same name. 

Option to ­paqfs are:

-c cachesize
The number of file system blocks to cache in memory. The default is 20 blocks.

­-d Output various debugging information to stderr.

­-i Use file descriptors 0 and 1 as the 9P communication channel rather than create a pipe. 

-m mtpt
The location to mount the file system. The default is /n/paq. 

-M mesgsize
The maximum 9P message size. The default is sufficient for 8K byte read message.

­-s Post the 9P channel on #s/paqfs rather than mounting it on mtpt.

­-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 system concatenated with additional data.
