Redhat version of "oracle-rdbms-server-11gR2-preinstall" for RHEL 6 (and not using the Oracle repo)?

The Oracle public repository has a RPM that preps a machine for the database software - tweeks the tunables, sets up users, downloades dependencies, etc.

Alas, the only way to get this package is to point to the Oracle public repositories - which I assume will effect our RH support. (Can anyone verify this support issue?)

Does Redhat have any plans on building such a package? The document Oracle Database 11g Release 2 on Red Hat Enterprise Linux 6 details everything that is recomended prior to installing the database - so it would basically be turning chapter 4 into an RPM.

Thanks,
