I interpreted this the same way. 

No, it's not a Linux-specific problem. Yes, it is a problem if you need
features in the enterprise application that you can't have because that
requires a newer kernel. No, it doesn't mean that Linux isn't 'enterprise
ready', it just means that vendors aren't keeping up, which as I
suggested, is only a problem if you're missing out on must-have underlying
OS features.

Which is the same for any platform Oracle (Peoplesoft et al) run on. It 
only becomse a 'Linux is not ready for the enterprise' problem when you 
don't have kernel-level features in situ that you absolutely need.

hehe.

I am also in discord with Andrew's comment about the disparity between
installs for Solaris and Linux. Explicitly:

 "The choice to move to Linux from Sun was prompted partly due to cost and 
 the applications " Blackboard (an online course content system) and the 
 Veritas clustering software  both run on Solaris so at least there would 
 no wasted knowledge investment if we needed to migrate back," he said. 
 "It took me two weeks to build the Linux clusters which would have taken 
 two days with Solaris."

I know many would claim the complexity of installs (particularly when you 
couple extended toolsets like Perl, Python, Apache and a hundred others) 
on a clustered Linux domain is far less than the corresponding Solaris, 
but that all boils down to what you are used to. YMMV. This isn't, once 
again, a problem with Linux.

I've cc:d Andrew Whyte in so he can respond. We may be mis-interpreting 
his notions and comments to the journalist.
