help

|
Saying Y here includes support for SquashFS 4.0 (a Compressed
|
|
Read-Only File System). Squashfs is a highly compressed read-only
|
|
filesystem for Linux. It uses zlib, lzo or xz compression to
|
|
compress both files, inodes and directories. Inodes in the system
|
|
are very small and all blocks are packed to minimise data overhead.
|
|
Block sizes greater than 4K are supported up to a maximum of 1 Mbytes
|
|
(default block size 128K). SquashFS 4.0 supports 64 bit filesystems
|
|
and files (larger than 4GB), full uid/gid information, hard links and
|
|
timestamps.
|
|
|
|
Squashfs is intended for general read-only filesystem use, for
|
|
archival use (i.e. in cases where a .tar.gz file may be used), and in
|
|
embedded systems where low overhead is needed. Further information
|
|
and tools are available from http://squashfs.sourceforge.net.

|
help
|
|
Saying Y here includes support for reading Squashfs file systems
|
|
compressed with XZ compression. XZ gives better compression than
|
|
the default zlib compression, at the expense of greater CPU and
|
|
memory overhead.
|
|
|
|
XZ is not the standard compression used in Squashfs and so most
|
|
file systems will be readable without selecting this option.
