The backport policy is flawed--but entrenched in Debian

Parent article: The trouble with backporting fixes

It all depends on the package and the change. If Debian has to fix xmms, it is probably easier to go to the latest and greatest that has the fix. If the problem is in glibc.. then having to recompile everything in Debian stable to use the latest glibc means a lot of work (plus other problems cropping up.)

Moving to later versions of glibc need not cause any such problems.

Nothing that depends on the older version needs to be recompiled, because the glibc ABI is enforcedly stable. Glibc uses ELF versioning to preserve old interfaces and semantics -- although they don't necessarily preserve old bugs that result in undocumented behavior.

That's to the good, because the programs get unexpected fixes, and only programs that depended on undocumented behavior get new problems. I.e. the ripple effect peters out fast.

You need to recompile everything (including all architectures) just to make sure that the new glibc version really works. And by "works" I don't mean that it would run software correctly, just that it can be used to build it.

If you really have to recompile everything to assure they work, something
is seriously flawed in our "shared object" implementation.
