I think it's statically linked so that it can be used for disaster
recovery.  If you somehow trash your shared library you can use rcp to copy
a new one from another machine on the net.

The "right" thing to do is to create a statically-linked version in /sbin,
but put a dynamically-linked version in /usr/ucb.
