how to relink /bin/sh away from dash -- update-alternatives?

[Robert P. J. Day]

  *sigh*.  it's embarrassing to ask trivial questions like this but,
sometimes, google just doesn't come through and i'm still feeling my
way around ubuntu.

  i'm setting up to build openembedded on my lynx box, and the sanity
check run by bitbake strongly recommends that i don't leave /bin/sh
linked to dash.  currently, there's a symlink /bin/sh -> dash.  but
i'm assuming this is managed by the "alternatives" feature, yet:

$ sudo update-alternatives --config sh
update-alternatives: error: no alternatives for sh.
$

  what am i screwing up?  i'm just about to run

$ sudo update-alternatives --all

to see what's happening.
