Hello, Thank you for the link to the FHS. And there is no doubt that was fairly silly of me (hence the « non-serious data loss »), I intended some data there to be kept for about one year, assuming the policy was to leave it up to applications to clean up. I reported this as a bug thinking about other users would might give systemd a go and who might not think, just like I did, that the default policy about temporary files might be different from the default policy in sysvinit.
As for the proper place to warn eventual other careless users, I would just like to say that I hadn't read README.Debian but https://wiki.debian.org/systemd before launching it the first time, which is why I suggested the debconf warning, but other places might admittedly be better suited. Another silly-users-friendly possibility would be triggering a warning at installation only if some files would be removed according to the default systemd configuration. Best regards Sam
