Thanks for starting this discussion!

NB, Conor's talk at LibrePlanet 17 who explains this in details already:

https://media.libreplanet.org/u/libreplanet/m/securedrop-leaking-safely-to-modern-news-organizations/

Given that Tails will probably remain relevant in the SecureDrop
ecosystem for a while (for example on the source's side), my intention
with this thread is to:

* Have more feedback from SecureDrop about the Tails in general,
hopefully opening communication channels that can be fruitful for the
future. I don't remember much discussion on public channels between
Tails and SecureDrop in the past.

* Understand what Tails should do to be more relevant in similar
contexts ("Tails for journalists and their sources").

I agree with "challenging". I partly disagree with "discouraged".

Sure, we've been discouraging people to shot themselves in the foot by
customizing Tails to the point of breaking it.

But we're also aware of the need for more customization and flexibility
withing Tails and have made steps in this direction:

- We published a statement in 2015 on how Tails derivatives should
work and how to collaborate:

https://tails.boum.org/contribute/derivatives/

- We got funding this year to work on a better support for storing
additional software in persistence which is so far only possible from
the command line and not on air-gapped machines:

https://labs.riseup.net/code/issues/14568

- We documented how to configure additional APT repositories:

I'd be interested in hearing Jen and Conor's take on this.
Would it make sense to have two options for the journalist workstation?
And I would totally understand if it doesn't make sense for them :)
