System calls on Linux are stable ABI. They have to be, because you can statically link libc. This is different from Windows.

I can (in fact, must when using MSVC) statically link kernel32.lib on Windows as well. It's not a C runtime/standard library, of course, but who ties their OS's user-level API to a particular implementation of a standard library of some random programming language anyhow?

I don't think a file can actually take less than 4 KiB of disk space on most popular file systems. Can it?
