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.
