Thank you. Because of two reasons, first I'm studying how to writing device drivers for FreeBSD and doing something like "Changing igb to foo in if_igb.c" could be very useful, second I want to change this name every where e.g. sysctl. Besides that doing this in rc.conf causes an extra boot time, and we are trying to decrease boot time. Please help about doing this job ...
