This is caused by sqlite3 (spell the prefix backwards). Exporting TMPDIR=/tmp when starting chromium works around it. Basically patching src/os_unix.c of the sqlite3 code to list /tmp before /var/tmp fixes this. I also reported this bug for the sqlite3 package now (#722699); but chromium seems to bundle its own copy of sqlite3, so it would be good to get this changed here as well. I'll let you know what the sqlite3 maintainer has to say. -- Julian Andres Klode - Debian Developer, Ubuntu Member See http://wiki.debian.org/JulianAndresKlode and http://jak-linux.org/. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

Bug#722571: chromium: Writes short-lived temp files to /var/tmp instead of /tmp
Package: chromium Version: 29.0.1547.57-3 Severity: normal Control: forwarded -1 https://code.google.com/p/chromium/issues/detail?id=290117 Chromium writes several short-lived files to /var/tmp, but those should be written to /tmp. Users with SSDs often mount a tmpfs on /tmp to reduce writes to the SSD. But /var/tmp cannot be a tmpfs, as it needs to be preserved across reboots. Writing those short-lived files to /var/tmp thus causes unnecessary writes to the SSD. -- System Information: Debian Release: jessie/sid APT prefers unstable APT policy: (980, 'unstable'), (500, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 3.10-2-amd64 (SMP w/4 CPU cores) Locale: LANG=de_DE.utf8, LC_CTYPE=de_DE.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages chromium depends on: ii chromium-inspector 29.0.1547.57-3 ii gconf-service3.2.6-1 ii libasound2 1.0.27.2-1 ii libatk1.0-0 2.8.0-2 ii libc62.17-92+b1 ii libcairo21.12.14-5 ii libcups2 1.6.3-1 ii libdbus-1-3 1.6.14-1 ii libexpat12.1.0-4 ii libfontconfig1 2.10.2-2 ii libfreetype6 2.4.9-1.1 ii libgcc1 1:4.8.1-10 ii libgconf-2-4 3.2.6-1 ii libgcrypt11 1.5.3-2 ii libgdk-pixbuf2.0-0 2.28.2-1 ii libglib2.0-0 2.36.4-1 ii libgnome-keyring03.8.0-2 ii libgtk2.0-0 2.24.20-1 ii libjpeg8 8d-1 ii libnspr4 2:4.10-1 ii libnss3 2:3.15.1-1 ii libnss3-1d 2:3.15.1-1 ii libpango-1.0-0 1.32.5-5+b1 ii libpangocairo-1.0-0 1.32.5-5+b1 ii libspeechd2 0.7.1-6.2 ii libstdc++6 4.8.1-10 ii libudev0 175-7.2 ii libx11-6 2:1.6.1-1 ii libxcomposite1 1:0.4.4-1 ii libxdamage1 1:1.1.4-1 ii libxext6 2:1.3.2-1 ii libxfixes3 1:5.0.1-1 ii libxml2 2.9.1+dfsg1-3 ii libxrender1 1:0.9.8-1 ii libxslt1.1 1.1.28-2 ii libxss1 1:1.2.2-1 ii xdg-utils1.1.0~rc1+git20111210-7 chromium recommends no packages.
