From 3d01e720ff7d33999e7c81481b860fae531c88f1 Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Sun, 20 Oct 2013 15:59:05 +0000 Subject: [PATCH] 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.
