# 1: Add -pipe to CFLAGS ( default optimization is -O2 )
# 2: Also change BIN_OWNER and BIN_GROUP from "root" to 0
# 3: Modify instructions using chown $(BIN_COMBO) to do a 
#    chown $(BIN_OWNER) and a chgrp $(BIN_GROUP) instead
# 4: makefile works with /dev/initctl, NOT $(ROOT)/dev/initctl
#    change this so it operates on our target root, NOT the hosts
# 5: alter mknod of $(ROOT)/dev/initctl to not set mode while creating the fifo
#    instead set mode with chmod.
