Oracle Database “incompatible” with Oracle Linux?

Today I gave a shot to install Oracle Linux. I thought I could easily install an Oracle DBA on it. Well, I was naive.

As only the 5.2 version is supported by XenServer 5.5, I downloaded that version of Oracle Linux. Installing it was surprisingly fast and easy, it asked almost nothing, and booted without any problems.

After this came the DBA, 10.2, which bloated an error message in my face saying that this is an unsupported version of Linux. Bah.

Is it only me, or is it really strange that Oracle doesn’t support their own distro?
