+Upstream-Status: Inappropriate [embedded specific]
+The FHS indicates that /etc must be capable of being mounted R/O.
+The FHS also indicates that lock files belong in /var/lock, and /var must
+be R/W as soon as possible during boot.
+This patch moves the mtab lock file from the potentially R/O /etc, to the
+R/W /var/lock area. This lock file is used when mounting disks and making
+other mount adjustments. The _PATH_MOUNTED_TMP is not adjusted, as failing
+to write to this file does not cause any functional limitations.
+(Note, if /etc is R/O, then /etc/mtab should be a symlink to /proc/mounts)
