I have automated installation for sles10 sp2 / oracle rac 10.2.0.4

Works fine but require a few unusial steps (not because of SuSE but because of RAC):

1) Upgrade to the kernel *39.3 (at least). original sles10 sp2 release had broken aio.

2) I am nlt sure about 11R but 10.2.0.1 had crs not cpompatible and had a bug in ocr fortmat. Solution - just copy files from 10.2.0.4. 11G don't have this
problem, more likely.

3) Starting with 11.1.0.7 and 10.2.0.4, oracle switched from hangcheck-timer to home-grown (!@#$) oprocd. By default, this beast wil kill the system after any minor delay (I find out that it kiils in pretty easy). So you must set up diagtimer 13 to make sure that oprocd runs with the margin 10 seconds and not 1/2 second.
You can find a lot on the internet.

4) The whole CRS is a mess of bugs, glitches and so on. Timeouts influence each other, oprocd had strange design and kills the system long before it is necessary for the fencing. If you worn on Vmware, you must disable oprocd totally; to make it al more funny, they change the variable DISABLE_OPROCD
meaning so that now 'true' means 'run it' and nkt 'skip it' and vice versa (so I just 'chmod a-x oprocd' and enabled old hangon timer on VMware).

In short, it is a lot of fun. I managed to install RAC in 3 hours from scratch, but it is 40 steps script (*whcih do it). Good point is that, not sure about 11.1.0.7, but 10.2.0.4 + CRS CPU patch + 88 database patches - do work well (after all).
