# Running Cwtch on Tails
:::caution Nightly Feature
2023-04-05 04:13:59 +00:00
This functionality is currently available in the [Nightly Release]( builds of Cwtch.
2023-04-05 04:13:10 +00:00
This functionality may be incomplete.
The following steps requires that Tails has been launched with an [Administration password](
Tails uses [Onion Grater]( to guard access to the control port. We have packaged
an oniongrater configuration `cwtch-tails.yml` and setup script (``) with Cwtch on Linux.
The tails-specific part of the script is reproduced below:
# Tails needs to be have been setup up with an Administration account
# Make Auth Cookie Readable
sudo chmod o+r /var/run/tor/control.authcookie
# Copy Onion Grater Config
sudo cp cwtch.yml /etc/onion-grater.d/cwtch.yml
# Restart Onion Grater so the Config Takes effect
sudo systemctl restart onion-grater.service
When launching, Cwtch on Tails should be passed the `CWTCH_TAILS=true` environment variable to automatically configure Cwtch for running in a Tails-like environment. (The `` does this)
## Persistence
By default, Cwtch creates `$HOME/.cwtch` and saves all encrypted profiles and settings files there. In order to save any profiles/conversations in Cwtch on Tails you will have to backup this folder to a non-volatile home.
See the Tails documentation for setting up [persistent storage](
