    # b/121354779: netd itself is not updatable, but on startup it dlopen()s the resolver library

    updatable

# Moved from external/android-clat/vendor-464xlat.rc. Since
# clatd is modularized and shipped in apex, migrate the
# clat vendor property to netd.
#
# Certain vendors disable 464xlat by setting a vendor property.
# The connectivity code in the Tethering APEX needs to disable
# 464xlat when the property is set, but it is only allowed to
# access non-vendor system properties. So copy the property to
# a property available to system APIs in android.sysprop.
#
# Arguably this script should live close to the code that uses
# it, but scrips in APEXes are not allowed to use "on property".
# So put it here close to clatd, which is at least related to
# 464xlat.
