I think that anything really vital should be statically linked. As I
see it, this would include a shell, mount, rm, cp, sync (!) and
perhaps tar (that's a killer) or dd.
The idea is that if you inadvertantly delete the shared lib apparatus,
or mangle one or more of your partitions, you should be able to restore
enough to get shared libs working again.
