Public bug reported:
TMPTIME setting from Wily is not migrated to mountall on upgrade to
Xenial.
systemd.postinst from 229-4ubuntu4 contains this bit:
# Do a one-time migration of the TMPTIME setting
if dpkg --compare-versions "$2" lt "204-9"; then
# Fix up potentially broken tmp.conf, see Debian#738862
if [ -e /etc/tmpfiles.d/tmp.conf ]; then
sed -i '/^# Clear \/var\/tmp/d' /etc/tmpfiles.d/tmp.conf
sed -i 's,^\(d /var/tmp\),#\1,g' /etc/tmpfiles.d/tmp.conf
fi
if [ -f /etc/default/rcS ]; then
. /etc/default/rcS
fi
if [ ! -e /etc/tmpfiles.d/tmp.conf ]; then
case "$TMPTIME" in
-*|infinite|infinity)
cat > /etc/tmpfiles.d/tmp.conf <<EOF
# Avoid clearing /tmp by shipping an empty /etc/tmpfiles.d/tmp.conf file
# which overrides /usr/lib/tmpfiles.d/tmp.conf.
# This file was automatically created because of local modifications in
# /etc/default/rcS where TMPTIME was set to infinite.
EOF
;;
esac
fi
fi
However, Xenial ships with a more recent systemd than 204, meaning that
the TMPTIME setting is not migrated. As a result people who upgrade from
Wily to Xenial will find that /tmp is always erased on startup, with no
clear indication of how to change the behavior.
Fixing this behavior would still expose this debian bug
<https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=795269> because the
(currently broken) code does not handle values other than infinity.
