Yes. There were a couple of issues with dietlibc but I have got help from
some people, including the dietlibc maintainer and now it build fine
on all arches, except hppa and arm, that it should not build on as
there is no reserved syscall.

I got a bug report on vserver-copy that it should have --numeric-ids added
to the rsync command to preserve permissions properly. It would be great
if that is added as well.
