The problem has been support for the OS and application vendor
certification.

We have heard this for a long time. Then one does a kernel upgrade to fix
some security issues. And then things begin to break.

   But you have testing/staging environment, right ? :)
   IMHO it is all about proper change management process to prevent
unexpected problems like this.

   P.S. Like you don't have a chance to break system by applying a
Solaris patch cluster ?

In my opinion, this has been solved now since RedHat
enterprise linux is around. You get the same support you would expect from
any commercial OS-vendor. And plenty of applications have been certified,
including Oracle.

I have no experience with them.
