// Namespace config for binaries under /postinstall.
// Only default namespace is defined and default has no directories
// other than /system/lib in the search paths. This is because linker calls
// realpath on the search paths and this causes selinux denial if the paths
// (/vendor, /odm) are not allowed to the postinstall binaries. There is no
// reason to allow the binaries to access the paths.
