This patch adds a image with squashfs as the root filesystem.
A rootfs_data partition will be generated on the first boot
and placed inside the rootfs partition (just after the squashfs
image).
advantages:
- it is possible to migrate from an existing -ext4
installation and back via sysupgrade.
- existing partition layout will not be lost.
- slightly smaller image size.
- support for attendedsysupgrade
disadvantages:
- needs f2fs + tools as well. This is because fs-tools decides on the
blocksize of the sdcard. So either f2fs or ext4 can get choosen as
the rootfs_data filesystem (depends on the size of the root partition).
- rootfs_data is placed into the rootfs partition. This makes
it difficult for tools that expect a /dev/mmc0pX device.
It also makes it difficult for data recovery tools since they
might not expect to find a embedded partition or will be
confused.
For people with existing build configurations: make sure to include mkf2fs
and f2fsck package into the image... Otherwise the new -squashfs image will
boot of a ram-overlay and won't keep the configurations after a reboot.

This is the buildsystem for the OpenWrt Linux distribution. Please use "make menuconfig" to choose your preferred configuration for the toolchain and firmware. You need to have installed gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff, unzip, gawk, getopt, subversion, libz-dev and libc headers. Run "./scripts/feeds update -a" to get all the latest package definitions defined in feeds.conf / feeds.conf.default respectively and "./scripts/feeds install -a" to install symlinks of all of them into package/feeds/. Use "make menuconfig" to configure your image. Simply running "make" will build your firmware. It will download all sources, build the cross-compile toolchain, the kernel and all choosen applications. To build your own firmware you need to have access to a Linux, BSD or MacOSX system (case-sensitive filesystem required). Cygwin will not be supported because of the lack of case sensitiveness in the file system. Sunshine! Your OpenWrt Community http://www.openwrt.org
