menuconfig FS_SQUASHFS
bool
prompt "squashfs support"
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.
config SQUASHFS_XZ
bool "Include support for XZ compressed file systems"
default y
depends on FS_SQUASHFS
select XZ_DECOMPRESS
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.
