Fair point. Have you spoken to sales about this?
It was sales answer at the time.

Selling Oracle on Fedora or Centos is not an option. Oracle doesn't support
them, so anyone who pays for Oracle will want to pay for RHEL.
Any dba worth its salt will tell you Oracle support is only a promise to
look at problems, and since problems are often workload dependent it's
no substitute to testing yourself your workload on realistic systems (ie
as close to production systems hardware/software wise as you can make
them). This is why big corps freeze OS/Oracle versions and test them
Now once you've beaten a system to death and verified Oracle likes your
CentOS/FC kernel/glibc versions (because they were the only ones you
could afford on test benches) the prospect of dropping it on an unknown
RHEL system can be more frightening than dispensing with Oracle support
(especially when it can be worked around with by having one RHEL system
somewhere, reproducing the bugs you can not cope with yourself here, and
then report them)
But since Arjan says RH got a dev program now I guess the problem is
partly solved (I hope he didn't think about the one where you have to
commit on supporting your app on a given RHEL version for five years -
for custom business apps that are evolving at a fast pace there is no
way anyone will sign on such a program).
