Depends. If the device is present when the system boots, yes. If it 
shows up later (like a USB drive) then you need to set up some 
/etc/devfs.rules instead.

devfs.rules are applied when you execute /etc/rc.d/devfs restart, and 
that may apply to devfs.conf too (never tried it honestly). That said, 
I've never had problems using chmod for temporary changes on device nodes.
