Considering the eye-watering memory recommendations that FreeNAS makes regarding using their software on a headless server, it's surprising that anyone would use it as the boot FS for a full-graphical workstation. I mean, it does really cool stuff, but most of that seems like overkill for a workstation. And even if Canonical is turning-off or turning-down a lot of the high-flying stuff in ZFS, it's still gotta be gobbling RAM like it's Christmas morning.
