Currently it's not possible to effectively mark a "firmware" partition as read-only. The sub-partitions "kernel", "rootfs" and "rootfs_data" are always created as read-write (ignoring the parent access mode). This patch enforces the access mode of sub-partitions to match the parent partition, which is useful for recovery images that are meant to be fully read-only to avoid accidental damage from end-user. An example of such implementation (read-only firmware image) is the recovery image used on the Zsun-SD100 [1]. Please note the related patch for fstools [2] to enable this read-only concept.

-----------------------------------------------------
This is the buildsystem for the OpenWrt Linux distribution.
To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.
You need gcc, binutils, bzip2, flex, python3.5+, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.
1. Run "./scripts/feeds update -a" to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default
2. Run "./scripts/feeds install -a" to install symlinks for all obtained
packages into package/feeds/
3. Run "make menuconfig" to select your preferred configuration for the
toolchain, target system & firmware packages.
4. Run "make" to build your firmware. This will download all sources, build
the cross-compile toolchain and then cross-compile the Linux kernel & all
chosen applications for your target system.
Sunshine!
