Я пытаюсь создать собственный дистрибутив, который запускает Docker. Я использую рамки киви, чтобы достичь этого. Установка Docker успешно выполнена во время сборки. Проблема в том, что я хочу загрузить несколько образов докера во время процесса сборки, чтобы система включала все необходимые образы при запуске. Проблема в том, что программное обеспечение KIWI использует chroot для запуска таких команд, как загрузка докера, вытягивание докера. Этим командам нужен работающий демон Docker. Когда я пытаюсь запустить демона, он всегда терпит неудачу. Я пробовал следующие вещи:
запуск docker через: systemctl start docker не удалось (systemctl по своему дизайну откажется от запуска службы в chroot-тюрьме)
запуск docker через: /usr/bin/dockerd также дает сбой и генерирует следующие журналы

Есть ли какая-нибудь техника для запуска docker-демона в chroot-джейле?
