FWIW, the nsswitch "problem" doesn't necessarily require you to go to
a dynamically-linked root and this was in fact one of the recent
topics of conversation on some of the freebsd lists.
Personally, I myself prefer the so-called "IPC" approach to doing
nsswitch. Namely, a daemon which is itself possibly
dynamically-linked and which may do caching, and where the libc code
talks to the daemon and has a local 'fallback' method.
FWIW, some guys at RSU (the russian RSU, Rostov State University)
claim to have some daemon code which puts us on the path towards
exactly the above-described model. This model does not require a
dynamically-linked root. I think that OS X does something along those
lines, too.
