Package: tmpreaper Version: 1.6.13+nmu1 The script /etc/cron.daily/tmpreaper searches for TMPTIME in /etc/default/rcS as a way to configure the ageing time of temporary files. Since Debian stretch, the systemd package no longer depends on "initscripts" package, which provides the /etc/default/rcS . Thus by default there is no such file, or it is empty as it happens to be on my test system.
Also the comments in /etc/tmpreaper.conf recommend setting TMPTIME in /etc/default/rcS. This may confuse newcomers when this file is no longer present. I suggest that a warning mechanism should be provided against this change, or possibly the dependence on /etc/default/rcS should be removed altogether in favour of /etc/tmpreaper.conf as the sole configuration file for tmpreaper.
