.SH DESCRIPTION
27 
.I Paqfs
28 
interprets the compressed read-only file system created by
29 
.IR mkpaqfs (8)
30 
and stored in
31 
.I paqfile
32 
so that it can be mounted into a Plan 9 file system.
33 
.I Paqfs
34 
is typically used to create a stand alone file system for
35 
a small persistent storage device, such as a flash ROM.
36 
It does not authenticate its clients and assumes each group
37 
has a single member with the same name.

.I paqfs
41

Suppress the output of the archive creation date and fingerprint to
58 
.IR stderr .
59

.BI -m " mtpt
61 
The location to mount the file system. The default is
62 
.BR /n/paq .
63 
.TP
64 
.B -s
65 
Post the 9P channel on
66 
.BR #s/\fIsrvname\fR ,
67 
default
68 
.BR #s/paqfs ,
69 
rather than
70 
mounting it on
71 
.IR mtpt .
72 
.TP
73 
.B -S
74 
The name to post in
75 
.BR #s .

The default is
77 
.BR paqfs .

.B -p
80 
Both post the 9P channel in

.B #s
82 
and

mount the
84 
.I paqfile
85 
in to the filesystem.
86 
.TP
87 
.B -v
88 
Verify the integrity of the
89 
.IR paqfile .
90 
Before mounting the file system, the
91 
entire file is parsed and the
92 
.I sha1
93 
checksum of the file system data is compared to the checksum embedded in the file.
94 
This option enables the use of
95 
.I paqfs
96 
with files that consist of a
97 
.I paq
98 
file system concatenated with additional data.
