Why do we need to copy data at all ?
Can't we just have an object file with pointers to other files ?
Like sure, if I ever want to ship my binary somewhere else, I'd like to do this. But for local interactive development, all the files are already in my local machine, so I don't know why we would need to create a second copy of them within some other file.
Hm, well what happens when you execv a executable then? Everything needs to get copied into ram and then jumped to, so you would be putting a linker implementation into a syscall right?
And if it's just as easy as concattening the files, them just do that in userspace.
