No, not at all like Debian. Debian doesn't have to try to match the
unattainable goal of 100% binary compatibility with an upstream source.
I've seen a small part of this first-hand, and deducing the build order
to gain binary compatibility is the one thing that can single-thread the
build process quicker than anything else. RHEL doesn't even have the
same need; an RHEL rebuild that didn't have the goal to be
bug-compatible near the 100% level doesn't, either, and can be built by
a lot of people.
Try it yourself: go back to CentOS 5.5 and attempt to rebuild the
released sources for 5.6 and get a binary compatible build. I've done
it myself for IA64; it was a pain.
All of the upstream distributions, Debian, Fedora, etc, have a lot of
latitude that CentOS never has enjoyed.
