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. Signed-off-by: Sven Eckelmann <sven@open-mesh.com> Signed-off-by: Gabor Juhos <juhosg@openwrt.org> SVN-Revision: 38483
