[DGD]building over the kernel

[Stephen Schmidt]

I have the impression, I think from something Dworkin once
said but I can't find it in the archives, that the kernel
lib is provided with the intention that one will build one's
mud on top of it. If one was to do that, how would one deal
with changes to core objects such as the user object. In one
very particular case, how would one deal with changing the
behavior of the "say" command, now hardcoded inside the
kernel? Would one have a new user.c, not inside the kernel,
that inherited the kernel's user.c and overrode the
receive_message() function? I notice that receive_message
is not nomask; is that (part of) the reason why?
