Agreed, another consideration is that it should be possible to load
software w/o using the shared libarary interface. This could give some
confidence to things like init (which can be supplied whole to reflect
changes) while other programs can chance the new shared library.

And, of course, the panic button of easily backing out of an
"upgrade", maybe a good rule of thumb would be that anything needed to
change it from single-user mode should be independantly resolved, or
an independantly resolved version should exist and be automatically
used for single user. Vendor's choice, I suspect the issues are subtle.

Let's face it, that's why pencils have rubout keys.
