Hi FreeBSD community 

Thank you all for replies. 

Yes, USB Mass Storage devices could be symlinked (may be others too) but 
ethernet devices cannot be symlinked but ethernet interfaces can be renamed. 

I have one more question, how do I know what device is attached to an 
ethernet interface after it is renamed?
