Then that's a problem with foo.rpm. We have this problem today -- i.e.,
you wouldn't be able to install foo.rpm today, even without
auto-dependency checking (because the RPM engine will do this dependency
checking, even if OSCAR does not). This is not new.

So this is a little more clear statement of the problem -- if ODA (for
example) depends on /bin/mysql, that would resolve to different RPMs on RH
and MDK. That's what you're saying, right?
I *think* autoupdate will handle this situation -- Jason, can you confirm?
But either way, the ODA RPM has to be built to handle whatever distro you
want to install that RPM on. If you build the ODA RPM to have
dependencies that can't be satisfied, then RPM will refuse to install it
-- regardless of whether OSCAR has explicit dependency checking or not.
