Don't read /data/local.prop on user builds Creating a root owned /data/local.prop is one of the most common ways to root an Android device. /data/local.prop is only intended to assist developers on debuggable devices, and is never intended to be used on production devices.

Change init to use libfs_mgr to mount filesystems. The new fs_mgr library moves much of the knowledge of what filesystems to mount into a new fstab.<device> file, and just calls one function to mount all the filesystems.
