And your solution to that is to run OpenFiler? I mean, there's nothing wrong with OpenFiler, but if all you need is an NFS share (which is all you need for ESX), the only thing it gains you is a configuration utility. There's certainly no one to blame.

I suppose you could go with Solaris instead. Sun developed NFS, there's support, and you can get an x86 box from them relatively cheaply.
