All of those concerns are what I hand-waved over with the "etc." :).
I found that the older {Net,Free}BSD-stable cfs/ sources were practically
identical to the NetBSD-current coda/ sources, with a small handful of
exceptions like the ones you mention. They were so identical, and the
exceptions so regular, that it was possible to write a program to
automatically convert the coda/ sources (back) into code that could run
on NetBSD-stable as well as -current, and possibly even on FreeBSD-stable.

When coda-5.0.1 came out and it didn't work with the older cfs/
sources, I thought "Well, the cfs/ sources must not be supported
any more. No problem, I'll just get the NetBSD-current coda/ sources
and make them work under -stable." So all of this happened before
I learned that you intended to (and had) updated the older cfs/ sources.
Since I'm happy with the results, I plan on continuing to track just
NetBSD-current coda/ and use it on the -stables. When things diverge
so much that I can't, I'll know :).
