This is great news to me, I can't thank the people working on the code 
enough, but still, thank you all.

The great news is that it has proven to be exceedingly reliable, and I have no hesitation in recommending it for busy workloads. All we need to do is add security updates and critical bug fixes on top and we'll be in a great position. No small feat I grant you, but we can start off small and work our way up.

Some have called for a stable branch after Illumos is integrated, but it could be many months until we have an Illumos dev build suitable for respinning as a stable branch. That's months of lost opportunity.

An example would be the recent Exim vulnerability on CentOS that allowed remote root access by sending appropriately formatted emails. This area is something where we will depend on users, not OI developers, alerting the project to the issue so that a judgement call can be made on whether we have the resources to fix the issue.

Potentially we have the option as a project of providing commercial support past the 6 month date if enterprises desired this. I feel this could be a good way of generating revenue for the project to fund development if there was a market for it.

> To make the above easier to manage, one proposal I have is to match the versions of Apache, PHP, MySQL, Tomcat etc to the same versions shipped in RHEL 6/CentOS 6. This way we can monitor their repositories for security updates against these packages, and share the same backports. This will make life a lot easier for us as a project.

I would suggest we keep a set of Zones on infra01.uk.openindiana.org around for doing this, so that doing a rebuild is very easy to do, and well documented. Just a case of logging in, patching the appropriate files, running a build, pushing to a test repo, testing it, and then pushing into the public repo.
