Singling out RHEL seems strange since I don't think SUSE or Canonical or Oracle is any different in this regard. If you are using something compiled on your own, you can't really expect a vendor to support it. Especially for the kernel, considering the enormous number of experimental options, flaky drivers, random third party patches etc, it would be a nightmare.

Quite. Note that if you have some module that you rely on that you need to use even when doing bug reproduction, but that is not included in the distro kernel, you can often take the distro config and kernel source and enable and compile that module, then load the module atop the distro kernel. This will usually work (modulo only those strange cases where enabling a module will also change code in the core kernel). (It's probably best to mention that you did this to the support people you're talking to, just in case it did break something, but I doubt that this approach will rouse too many hackles.)

RHEL is the leader in the "enterprise Linux" market, and as such, to a large extent their example drives that segment of the market.
That's why I specifically mentioned them, even though Suse and Oracle have the same policies (I don't know about Canonical)
