TAILS: Instalação persistente do pacote deb em cada inicialização

Question

Eu quero instalar aplicativos persistentes em cima de caudas. a maneira como funcionaria é que ele seria instalado toda vez que as caudas fossem ativadas. Como fazer isso? Pelo que entendi:

eu criei /live/persistence/TailsData_unlocked/apt-sources.list.d/mydebs.list

então

sudo apt install dpkg-dev

então

dpkg-scanpackages -m . | gzip -9c > Packeges.gz na pasta home/amnesia/Persistent/setup contendo arquivos .deb

então adicionado:

deb [trusted=yes] file:///home/amnesia/Persistent/setup ./ em mydebs.list

então adicionado:

dpkg-dev /etc/apt/sources.list.d source=apt-sources.list.d,link em sudo gedit /live/persistence/TailsData_unlocked/persistence.conf

Depois disso eu faço: sudo apt update
