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.
