| INSTALLING SQUASHFS |
| |
| The squashfs1.3r3.tar.gz file contains this file, a README file, |
| an ACKNOWLEDGEMENTS file, a CHANGES file, the squashfs patch directories/files, and |
| the squashfs-tools directory (mksquashfs). |
| |
| 1. Patching the kernel |
| ---------------------- |
| |
| There are six kernel patch directories depending on your linux kernel version. |
| In each directory there are patches to provide squashfs1.3 release 3 support |
| from a base kernel, and an incremental upgrade patch that upgrades a |
| squashfs1.3r2 patched kernel to a squashfs1.3r3 kernel (except for 2.4.24 and |
| 2.6.1). |
| |
| To patch your kernel, cd into the top level directory, and run the "patch" |
| comand, e.g. assuming linux-2.4.20 |
| |
| %cd /usr/src/linux-2.4.20 |
| %patch -p1 < location-of-squashfs/linux-2.4.20/squashfs1.3r3-patch |
| |
| Where "location-of-squashfs" is the path to the squashfs1.3r3 source directory. |
| |
| The squashfs patches patch the relevant kernel files to add configure support, |
| initrd support, include files, and the squashfs directory under linux/fs/. |
| Once patched, the kernel must be reconfigured, with squashfs support turned on |
| (either Y/M) to ensure that inflate support is built into the kernel. The |
| squashfs kernel option can be found in the filesystems submenu of the |
| configure menus. In the 2.6.1 kernel, the squashfs option is hiding in |
| the new miscellaneous filesystems submenu near the bottom of the filesystems |
| submenu. |
| |
| 2. Building squashfs tools |
| -------------------------- |
| |
| The squashfs-tools directory contains the mksquashfs program. This can be |
| made by typing make. The source files use a local copy of squashfs_fs.h |
| (included in the kernel patches) allowing the tools to be made without needing |
| to patch the kernel. The program uses Large File Support |
| (64 bit offsets etc.) and so a relatively recent glibc is needed. |
