I will generalize and maybe deviate to the point of being off topic.
I recently had to set up an IPsec LT2P VPN server with radius authentication.
I tried to do that with FreeBSD and spend almost a full day. I used 4 different KERNELS combined with
security/ipsec-tools or
security/strongswan. In all cases the results did not meet my requirements. I had to make this work for OSX, Windows7, IOS and Android clients.
It took 20 minutes to make that work with Ubuntu 12.04
I am also involved in building ZFS based storages. I can safely say that my experience with ZFS has evolved a lot since FreeBSD 8.0-RELEASE. Yet I struggle daily to deal with issues that are only addressed in CURRENT and (maybe) MFC to STABLE. I am seriously considering of switching to Oracle and pay the license instead of having to deal with stupid issues that should have been already solved.
Most of my clients demand stability. Stability and bureaucracy often go along. Using a Prerelease or Beta or RC for months might sound like a good choice to us. But for high rank IT personnel, who need to cover their ass, this is a no go situation. For the shake of the argument please have a look at the differences in code between RC1 & RC2.
Journal UFS2. It was finally released in FreeBSD 9.0-RELEASE. But wait, there is a bug and you can not backup a UFS2+J fs!!! Ok, has it been fixed? Yes but we don't issue an errata because it is not a security issue!!!
A new next generation package management tool is announced and it is supposed to be the default for FreeBSD 9.1-RELEASE. But wait, we don't have enough mirrors to support it!!!
The list can go on and on and on... The point is not to blame the developers who are involved here. A foundation is supposed to be behind all this to support and fund the project. Because a project can not survive without a project manager. And because a successful project is a project that is being used.
I don't care if you produce the best car in the world. If no one is driving it then you have nothing.
Just some bitter thoughts from a FreeBSD advocate.
