Whoa! What I'm talking about is a nuthead who might have written quite a
lot of his own programs, which are dynamically linked against a shared
library, and that would be a shared library with both the major and
minor version number registred.
Now, if he were to have linked it static, things would work just fine
when he upgrades, but if he linked it dynamic, he'd be borked, since we
remove shared libraries, because we think that noone will need them. I'm
questioning if that is a wise conclusion.
It don't have anything to do with anything else in the NetBSD
distribution, so don't bring /etc, and other parts of the parts
delivered by NetBSD into it.
