.SH DESCRIPTION
|
|
|
|
|
.I Mkpaqfs
|
|
|
|
|
copies files from the file tree
|
|
|
|
|
.I source
|
|
|
|
|
(default
|
|
|
|
|
.BR . )
|
|
|
|
|
to the
|
|
|
|
|
.IR paqfs (4)
|
|
|
|
|
file system archive
|
|
|
|
|
.IR file .
|
|
|
|
|
.PP
|
|
|
|
|
The files and directory structure are divided into
|
|
|
|
|
.I blocksize
|
|
|
|
|
(default
|
|
|
|
|
.BR 4096 )
|
|
|
|
|
byte blocks.
|
|
|
|
|
Larger blocks make large files more compact but take longer to access.
|
|
|
|
|
.I Blocksize
|
2013-05-03 11:57:00 +00:00
|
|
|
must be in the range of 512 bytes to 512K bytes.
|
2011-03-30 13:49:47 +00:00
|
|
|
If the
|
|
|
|
|
.B -u
|
|
|
|
|
option is set, the blocks are not compressed.
|
|
|
|
|
Otherwise each block is compressed using the
|
|
|
|
|
.IR flate (2)
|
|
|
|
|
compression algorithm.
|
2021-05-23 15:06:14 +00:00
|
|
|
The compression level can be set using the flags
|
|
|
|
|
.B -1
|
|
|
|
|
to
|
|
|
|
|
.B -9
|
|
|
|
|
(defaults to
|
|
|
|
|
.BR -6 ).

|
|
|
The
|
|
|
|
|
.B -l
|
|
|
|
|
option embeds a label of up to 32 bytes within the file header and may be
|
|
|
|
|
useful for identifying the file system.
