@gigantos I read the thread, and I agree with you that Luca's tone is (way) out of line.
The other people in the discussion (including Lennart Pottering, who is, if you didn't know, the creator of systemd) are respectful and contribute positively to the discussion.
@karl I am just disappointed, that's all. And refuse to believe there were no alternatives to tempfiles.d, such as an additional directory.
