It's even worse than that. For example, Red Hat has on a couple of occasions
provided update packages. Those packages were built on systems where they
had applied all their other patches. This is often necessary when they update
a critical system library. If someone tried to upgrade such a patched system
with a package built on a base-line (i.e. unpatched) system, they'd get
version conflicts. On the other hand, upgrading a base-line system with a
package built on a patched system also generates version conflicts.
Are you sure the kernel and compiler versions are recorded? I know the
versions of the system libraries used are recorded, but I don't remember
seeing kernel or compiler version conflicts. However, I've only done the
package build bit twice for samba, so I could easily have missed something.
Does this describe the proper procedure:
1) Declare a version freeze -- identify what is going into a particular
version and what is NOT going into that version.
2) Basic tests on the new version -- it better compile on the development
system or nobody's going to get it to work.
3) Build a complete set of packages on the distribution system, patches and
all. These binaries are not necessarily for public consumption. The
.src.rpm is what is important.
4) Test the package as an upgrade to an existing system. Test that the package
removes itself properly. Test the package as a 'clean' installation.
Basically, this makes sure all the pieces are included in the package.
5) Build the distribution binaries on the various base-line systems. The
.src.rpms built in step 3 should be used to do this. Install the
resulting packages on the build system to make sure they really did
6) Clean up the build systems so they can be used again.
Step 5 is the bear!
