There was always a problem; there where just less people running into
it, because yum/dnf installed "kernel-devel" most of the time, which
matched the kernel that was running on most systems; but quite a few
x86-32 users ran into problems afaics, as kernel-PAE get's installed
there sometimes and hence they needed kernel-PAE-devel.

Mosts of the docs and howtos on the net don't mention that, which leads
to confused and frustrating users; those in the end might be one of
multiple problems why they switch to another distribution.

That's not a solution, that's solving the problem for some users and
ignoring others (those that use kernel-PAE for example).

"The kernel-devel package that matches the installed kernel(s)" would include kernel-PAE-devel matching kernel-PAE, in this fantasy land I invented.
