I guess I totally assumed busybox was being used, so good suggestion.
I too saw this with an older version of busybox (0.60 maybe?) and I
ended up editing the config to contain only init and then compiled it
statically and placed it on the rootfs.  It turned out to be just the
right size and functionality for my needs.  I think I later updated to
a 1.0 or 1.1-series and didn't have to use the same hack.
