I really like (and have used in production) the ability to run Solaris Zones (containers) and "LX zones" which are Linux containers side by side on the same hardware.

Many installation problems show up in the handling of USB3 and related quirks; I have a lovely AMD 8350 system that I can't install from USB onto because of some XHCI problem. The USB stick will boot the kernel, but then the kernel can't properly handle the USB stick after it has booted and can't see the installation media. I suppose I should bite the bullet and burn a CD to boot from, which should fix it.

That shouldn't be a fundamental problem with current Tribblix - due to this sort of problem the installer got modified so that once the bootloader has pulled the ramdisk off the usb stick it doesn't need it again (although if it can't see it it won't be able to install any packages from it, falling back to dragging them across the network).

Why not use a PxE server? Mostly simple to setup.
