Qual é o significado dessas perguntas do debconf?

Como você pode ver o resultado de debconf-get-selections | grep phpmyadmin:

# MySQL application password for phpmyadmin:

Então, o que são esses?:

phpmyadmin      phpmyadmin/mysql/admin-pass     password
phpmyadmin      phpmyadmin/setup-password       password

Isso .../mysql/admin-passé para debian-sys-maintque seja gerado automaticamente? dbconfig-common não faz nenhuma pergunta sobre essas senhas, não é? Eu pesquisei as fontes do phpmyadmin, então pode estar usando o modelo debconf para bancos de dados, não é? Então, depois disso, procurei fontes debconf para este modelo e havia essas linhas para admin-pass( ou seja, aqui ), mas provavelmente seria mais eficaz se aqui houvesse alguém que soubesse exatamente o que elas significam.
