I agree that PC-BSD generally doesn't need to be rebooted, but that doesn't help people using their machines at home who want to power-off at night. My PC-BSD machine is using UFS and I find it takes about two minutes or so for the machine to go from power-on to login screen. My Linux OS, running on the same hardware, takes around twenty seconds.
I'd love to see PC-BSD's boot time cut in half. Recently I tried OpenBSD on the same hardware and found it booted in under a minute. Granted, it starts relatively few services.
