The short version is that we need install tools just like we have build tools now. The long version is this: Problem: It would seem from Asmodai's breakage that installworld assumes that it is ok to use the existing binaries on the system in /bin /usr/bin, etc. to install the new ones. However, if you have a rare case like this where the old and new libs/progs are incompatible, then there is a window between the installation of the different parts where you can get screwed. For example, here the new libc gets installed, which doesn't have the 'strings_to_flags' call. The old install program (not yet replaced) tries to call the 'string_to_flags' function which was present in the old libc but which isn't around anymore. Boom! Solution: We need statically built install tools just like we have build tools. I think we should use the newer versions (i.e. static versions of the ones we just built under /usr/obj during buildworld that are linked against the new libraries), rather than doing some fancy footwork to make the existing binaries work. We already do this with the build tools. By using the newer binaries we only have to maintain one interface in our Makefiles to the install tools: whatever their current interface is in /usr/src.
