I accidentally Nexenta
I really do not know why I happen to have a soft spot for Solaris, which is no more, may it rest in peace. But for some reason, I always felt it could be as good as Linux. But then, release after release, it never quite is.
Nexenta Core Platform is an OpenSolaris-based system with a Ubuntu application base and the flexible and powerful APT package management. Sounds like a marvelous idea.
Booting and all that
You get a simple GRUB and then you're straight into the installation, no live experience. This is not a good thing if you like to battle-test your hardware compatibility. Moreover, Nexenta wants to install itself on the entire disk, so woe any other operating system you may have there. For this reason, I did not perform a physical installation and went for a virtual machine instead.
