			INSTALLING SQUASHFS

1. Kernel support
-----------------

This release is for 2.6.29 and newer kernels.  Kernel patching is not necessary.

Extended attribute support requires 2.6.35 or newer kernels.  But
file systems with extended attributes can be mounted on 2.6.29 and
newer kernels (the extended attributes will be ignored with a warning).

XZ compression support requires 2.6.38 or newer kernels.

LZ4 compression support requires 3.11 or newer kernels.

ZSTD compression support requires 4.14 or newer kernels.

2. Building squashfs tools
--------------------------

The squashfs-tools directory contains the source code for the Mksquashfs and
Unsquashfs programs.  These can be compiled by typing make (or sudo make
install to install in /usr/local/bin) within that directory.

2.1 Compressors supported

By default the Makefile is configured to build Mksquashfs and Unsquashfs
with GZIP suppport.  Read the Makefile in squashfs-tools for instructions on
building LZO, LZ4, XZ and ZSTD compression support.

2.2 Extended attribute support

By default the Makefile is configured to build Mksquashfs and Unsquashfs
with extended attribute support.  Read the Makefile in squashfs-tools for
instructions on how to disable extended attribute support, if not supported
by your distribution/C library, or if it is not needed.

2.3 Reproducible builds

By default the Makefile is configured to build Mksquashfs with reproducible
output as default.  Read the Makefile in squashfs-tools for instructions
on how to disable reproducible output as default if desired.
