Gabor Juhos 80a15fe8ad ar71xx: Fix sysupgrades for Allnet and OpenMesh devices 
Both Allnet and OpenMesh sysupgrade uses fw_setenv from uboot-envtools to
change different settings in the uboot environment. uboot-envtools version
2013.01 introduced a filesystem lock "/var/lock/fw_printenv.lock" to guarantee
mutually exclusive access to the uboot environment. But the path /var doesn't
exist on the sysupgrade ramfs.

An upgrade on these devices fails since r36033 ("[package] uboot-envtools:
upgrade to version 2013.01.01") with following messages:

 Error opening lock file /var/lock/fw_printenv.lock
 failed to update U-Boot environment

Creating the "/var/lock" path before running fw_setenv is therefore a
requirement unless the locking functionality in fw_setenv is removed or
replaced with optional locking.

README 

This is the buildsystem for the OpenWrt Linux distribution.

Please use "make menuconfig" to configure your appreciated
configuration for the toolchain and firmware.

You need to have installed gcc, binutils, bzip2, flex, python, perl
make, find, grep, diff, unzip, gawk, getopt, 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.

You can use "scripts/flashing/flash.sh" for remotely updating your embedded
system via tftp.

The OpenWrt system is documented in docs/. You will need a LaTeX distribution
and the tex4ht package to build the documentation. Type "make -C docs/" to build it.

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.
