I reckon the logo on Linode Wiki needs a change. Via Linode’s latest blog post, it is now possible to roll your own operating system with Linode’s pv-grub support. There’s even a tutorial on wiki on how to install NetBSD, although it’s far from “click and deploy” like its Linux Xen VPS offerings.
Besides a few earlier failed attempts to install FreeBSD and a few years of experience with Mac OS X, I am completely clueless on getting a xBSD box up and running. I’ll probably go for something like RootBSD‘s Xen-based FreeBSD 7.0 VPS (which I presume will be much easier to set up than Linode’s) if I ever want to get into the daemon land.
