Document the syntax and use of /live/persistence/TailsData_unlocked/persistence.conf
Only today, I felt like explaining persistence.conf would have helped 2 advanced use cases:
- On #18160, @hefee wants to persist .local/share/TelegramDesktop to use Telegram in Tails.
- On https://t-hinrichs.net/DinoTails/DinoTails_buster-backports.html, Timo wants to persist .local/share/dino to use Dino in Tails.
- Dotfiles allow persisting single files but not entire folders.
- persistence.conf would allow persisting entire folders.
Similar warnings as what is being discussed on #18232 would apply but I'm wondering if it would be significantly different to document
