I don't know (I work for Red Hat, but am not directly involved with
internal builds), but I am highly skeptical of the claim.
That said, why not ask whoever wrote that doc for some kind of
citation or proof? They say something about testing, so perhaps they
have some proof of this?
It was deduced experimentally during early -- for some value of early --
CentOS development. I'll suggest the reference to Red Hat is changed.
It could be important to know if it was correct now, which was a reason
for asking here. I assume that rebuilds are essentially the same as
RHEL (modulo reproducible builds) when it comes to things like reporting
bugs and issues relevant to EPEL development. Specifically I assume
they won't potentially have different code generation bugs.
