systemd's postinst does a one-time migration from TMPTIME in /etc/default/rcS to /etc/tmpfiles.d/tmp.conf , if the former has tmp wiping disabled. That migration, however, doesn't handle the case of TMPTIME set to a non-zero, non-infinite value. It should be possible to do so, by copying /usr/lib/tmpfiles.d/tmp.conf to /etc/tmpfiles.d/tmp.conf by way of a sed that changes the '-' on the D line to ${TMPTIME}d, assuming TMPTIME is numeric. The following patch to systemd.postinst *should* work (not tested). --- /var/lib/dpkg/info/systemd.postinst 2015-08-01 05:20:45.000000000 -0700 +++ /tmp/systemd.postinst 2015-08-12 10:33:21.108381657 -0700 @@ -72,6 +72,15 @@ # /etc/default/rcS where TMPTIME was set to infinite.
