This shows you have enabled the legacy version ID option in the kernel,
but your utils weren't configured with any legacy APIs and thus are
unable to do anything.

You'll either have to disable the legacy version ID (why did you enable
that in the first place?), or recompile your utils with
--enable-apis=NOLEGACY passed to ./configure.
