This is of course not the purpose of your post, but since you're interested in this topic, I wanted to mention that you can now create memory-backed files on linux using the memfd_create syscall without using any filesystem (nor unlink) and you can also execute them without the /proc/self/fd trick by using the execveat syscall. In glibc, there is fexecve which uses execveat or falls back to the /proc trick on older kernels.
You're entitled to your opinion, of course - language is subjective afterall - but the meaning of the word "hacking" as I'm using it comes from the MIT hacking community as described by Richard Stallman [0] [1].
I agree. I was looking into how you start a child process in C++ recently and I was surprised and not at all surprised to find that the answer is still fork and execve. Ridiculous.
