I guess the build system should be more tolerant of this, but
there are bound to be problems regardless. I don't see why
the install tools can't also either have their own set of
libraries (utilizing LD_LIBRARY_PATH) or be built static.

If you are going to remove the interim versioned symbols, that's
OK with me, but what are you going to do for the people that miss the
transistion period (after the interim symbols are removed)? Shouldn't
the build system work regardless? If I understand correctly, I think
the more general problem is that the install tools are dependent on
working with new libraries.

It should be easy to say FBSD_1.0 is RELEASE_7.0, FBBSD_1.1 is RELEASE_7.1,
etc. The versioned symbol namespace is mostly to aid the release
engineers. If you start to have FBSD_1.2, FBSD_1.3, and FBSD_1.4
are interim versions and FBSD_1.5 is release 7.1, that isn't good.
Again, I highly doubt you would have Sun or even Linux have interim
versions that are made public. If you want to have interim versions
and then remove them at a later point before a release, that is a
different story, but it doesn't solve the problem for someone missing
the transition period, whereas a more general solution would.
