This line of reasoning doesn't make any sense, or at least it's not 
related to what I was talking about. Let me try phrasing it a different 
way: 'diskutil eject foo' will kick the disk off an OSX system and 
remove its entry from /dev, and this functionality works across all 
devices and adapters regardless of make or model. Whatever the 'eject' 
command is doing, it's clearly entirely software side within the OS*. 
Being software, FreeBSD should be capable of the same, especially 
considering both OSs have such a close common heritage.




*(unless you're claiming all devices everywhere have implemented 
mac-specific commands in their firmware, but that wouldn't really make 
sense either since if it's everywhere any other OS could use it too)
