Yes, I'm aware of that. Two mitigating factors apply here:
- ELF has no idea what a "major number" is. That's only a versioning
convenience introduced by the -soname attribute of a shared object. In
reality, ELF ld(1) only looks at the unversioned .so when linking, and
this will always point to the correct "current" version of the package.
- a.out, where version numbers do come into play, is harder to deal with,
but its installed base is now somewhat small. Regardless, so long as the
old versions of libraries are properly uninstalled when replacing them
with the new versions, this still won't be a problem.
(From what I can tell of the Darwin linker commands, it's much more ELF-like
in concept, in that an unversioned .dylib exists with information about the
