I know it is possible to bring down lo interface by doing
ifconfig lo down. But is it possible to configure the kernel that the lo interface will simply not be available? Please note that I don't want to remove kernel source code or disable the entire tcp/ip stack.
Note that this is entirely a technicality question. I know one needs the interface and a lot of bad things will happen to my machine. But I'd still like to know if it's possible at all.
