SH DESCRIPTION
I Paqfs
interprets the compressed read-only file system created by
IR mkpaqfs (8)
and stored in
I paqfile
so that it can be mounted into a Plan 9 file system.
I 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.
PP
Options to
I paqfs
are:
TP
BI -c " cachesize
The number of file system blocks to cache in memory. The default is 20 blocks.
TP
BI -M " mesgsize
The maximum 9P message size. The default is sufficient for 8K byte read message.
TP
B -d
Output various debugging information to
IR stderr .
TP
B -i
Use file descriptors 0 and 1 as the 9P communication channel rather than create a pipe.
TP
B -q
Suppress the output of the archive creation date and fingerprint to
IR stderr .
TP
BI -m " mtpt
The location to mount the file system. The default is
BR /n/paq .
TP
B -s
Post the 9P channel on
BR #s/\fIsrvname\fR ,
default
BR #s/paqfs ,
rather than
mounting it on
IR mtpt .
TP
B -S
The name to post in
BR #s .
The default is
BR paqfs .
TP
B -p
Both post the 9P channel in
B #s
and
mount the
I paqfile
in to the filesystem.
TP
B -v
Verify the integrity of the
IR paqfile .
Before mounting the file system, the
entire file is parsed and the
I sha1
checksum of the file system data is compared to the checksum embedded in the file.
This option enables the use of
I paqfs
with files that consist of a
I paq
file system concatenated with additional data.
