>> that is simply FUD

You should educate yourself about FUD, I recommend the Halloween documents, where they explain the unfeasibility of FUD tactics against an open source project, and that if someone tries to do it they won't get anywhere.

They don't buffer into /dev/null... until you fill the buffer.

And the purpose of systemd, as near as I can tell, appears to be making my system into a Windows box, complete with binlogs.

No, when the buffer is full, the write() call blocks. Otherwise no UNIX pipes could ever reliably transport data.

True, I was wrong here.
