Me

• a tiny bit Debian contributor
• Tails contributor (doc, bug triaging, community stuff, user support, reports writing, press, and speaker sometimes :))

• not a developer. I know about Tails design and plans, but don't ask implementation questions :)

Tails

• The Amnesic Incognito Live System: https://tails.boum.org
• Live system (USB, DVD, SD card)
• use the Internet anonymously, circumvent censorship: all connections to the Internet are forced to go through the Tor network
• leave no trace on the computer you are using unless you ask it explicitly
• works on (almost) any x86 computer
• based on Debian ♥

Relationship to Debian

• Debian is our "base" and we add some Tails-specific things
• we try to keep this changes (the "Delta") as small as possible because:
• it's work to maintain it and we're few people
• it's better if everybody benefits from our improvements
• ... and we succeed: less modified packages in Tails/Wheezy than in Tails/Squeeze, will be even better in Tails/Jessie
• Debian is a great upstream :)

What did we do upstream?

• AppArmor (Ulrike did a OPW in Debian for it)
• libvirt
• Seahorse
• fix OTR downgrade → v1
• various Debian things (including Debian Live)

What we did not do internally

... despite pressure:

• grsecurity
• compile-time hardening

What we did internally

... and are in the process of sharing:

• OpenPGP applet
• erasing memory on shutdown
• testing framework (cucumber, sikuli, libvirt)

In Debian

• We use usertags in Debian's bugtracker https://bugs.debian.org/
• user =
• tags: whatever we need, that's our namespace (e.g. crypto-gui, hardening, im)
• all our usertagged bugs: https://udd.debian.org/cgi-bin/bts-usertags.cgi?user=tails-dev@boum.org
• documentation: https://wiki.debian.org/bugs.debian.org/usertags

In Tails: Redmine

Tails work that needs to be done in Debian: https://labs.riseup.net/code/projects/tails/issues?query_id=138

Help maintain backports

• we use a lot of backports
• e.g. poedit, libvirt, qemu, redmine, monkeysign
• we could use more, e.g. the Xorg stack

Help maintain packages

• mat
• libgsecuredelete and nautilus-wipe
• OTR-related packages: https://wiki.debian.org/Teams/OTR
• anonymity-related packages: https://wiki.debian.org/Teams/AnonymityTools
• anything Tails relies upon, e.g. GNOME
• anything our infrastructure uses, e.g. libvirt/qemu, Jenkins, ruby-rjb, Puppet

Distribution-wide improvements

• AppArmor support: https://wiki.debian.org/AppArmor
• Reproducible builds: https://wiki.debian.org/ReproducibleBuilds
• Hardening: https://wiki.debian.org/HardeningWalkthrough
• Keep Debian Live development branches good enough for our needs, e.g. via automated testing.
• Keep Debian awesome.
