read through the source for the two packages above. ifconfig on my machine
is 33k but if your config will be locked down, you can sum it up as

socket(PF_INET, SOCK_DGRAM, IPPROTO_IP) = 4
ioctl(4, SIOCSIFADDR, 0xbffffb78)       = 0
ioctl(4, SIOCSIFNETMASK, 0xbffffb68)    = 0

to set the address and netmask of the loopback interface. 

read the source of the utils or strace them. if you have a few utils like
mount and ifconfig you can combine them into one program to cut down on
overhead and check the argv[0] to see what name they were called with and
change behavior based on that.

When they took the Fourth Amendment, I was quiet because I didn't deal drugs.
When they took the Fifth Amendment, I was quiet because I was innocent.
When they took the Second Amendment, I was quiet because I didn't own a gun.
Now they've taken the First Amendment and I can't say anything.
