* What led up to the situation?
A bunch of reasonably important iceweasel-downloaded .pdf files in /tmp suddenly disappeared. I feared that I had misconfigured the /etc/tmpfiles.d/tmp.conf and allowed automatic cleaning, but that file was correct (prevented /tmp cleaning): # Automatically migrated from TMPTIME in /etc/default/rcS #d /var/tmp 1777 root root - d /tmp 1777 root root - The syslog at around the time of the oldest remaining /tmp file showed what had instead happened: Dec 11 07:24:57 insight dbus[671]: [system] Activating via systemd: service name='org.freedesktop.hostname1' unit='dbus-org.freedesktop.hostname1.service' Dec 11 07:24:57 insight systemd[1]: tmp.mount: Directory /tmp to mount over is not empty, mounting anyway. Dec 11 07:24:57 insight systemd[1]: Mounting Temporary Directory... Dec 11 07:24:57 insight systemd[1]: Mounted Temporary Directory. Dec 11 07:24:57 insight systemd[1]: Starting Hostname Service... Dec 11 07:24:57 insight dbus[671]: [system] Successfully activated service 'org.freedesktop.hostname1' Dec 11 07:24:57 insight systemd[1]: Started Hostname Service. I had run 'hostnamectl' at around 7:24am, which activated the org.freedesktop.hostname1 service, which then, via the 'PrivateTmp=yes' line in dbus-org.freedesktop.hostname1.service used tmp.mount, which put /tmp on tmpfs. I got back my /tmp files by unmounting /tmp, so all was well. But how should I prevent it from happening again? I don't want /tmp on tmpfs. Should I just set PrivateTmp=no in that config? I read bug #779902 and the patch in its msg #32 <https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=779902#32>, but I am still confused about whether setting it to No has other bad effects. *** End of the template - remove these template lines *** -- System Information: Debian Release: stretch/sid APT prefers testing APT policy: (990, 'testing'), (500, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.2.0-1-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.utf8, LC_CTYPE=en_US.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages systemd depends on: ii adduser 3.113+nmu3 ii libacl1 2.2.52-2 ii libapparmor1 2.10-2+b1 ii libaudit1 1:2.4.4-4 ii libblkid1 2.27.1-1 ii libc6 2.19-22 ii libcap2 1:2.24-12 ii libcap2-bin 1:2.24-12 ii libcryptsetup4 2:1.6.6-5 ii libgcrypt20 1.6.4-3 ii libkmod2 21-1 ii liblzma5 5.1.1alpha+20120614-2.1 ii libmount1 2.27.1-1 ii libpam0g 1.1.8-3.1 ii libseccomp2 2.2.3-2 ii libselinux1 2.4-3 ii libsystemd0 228-2 ii mount 2.27.1-1 ii sysv-rc 2.88dsf-59.2 ii util-linux 2.27.1-1 Versions of packages systemd recommends: ii dbus 1.10.4-1 ii libpam-systemd 228-2 Versions of packages systemd suggests: pn systemd-container <none> pn systemd-ui <none> Versions of packages systemd is related to: ii udev 228-2 -- no debconf information
