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

|
||
|
|
file systems with extended attributes can be mounted on 2.6.29 and
|
||
|
|
newer kernels (the extended attributes will be ignored with a warning).
|
||
|
|
|
||
|
|
LZO compression support requires 2.6.36 or newer kernels.
|
||
|
|
|
||
|
|
XZ compression support requires 2.6.38 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.
