As I read the glibc faq, linux-headers are backwards-compatible as far
as glibc is concerned; that is, newer linux-headers still have
everything needed to make glibc work with older kernels. And I assume
that holds for other packages which need linux-headers, not just glibc.
Whether my understanding of why is correct or not, the glibc folks do
recommend using the latest linux-headers, even if your kernel is older.
