không thể khởi động docker khi sử dụng chroot

Tôi đang cố gắng xây dựng một bản phân phối tùy chỉnh chạy docker. tôi đang dùng khung kiwi để đạt được điều đó. Cài đặt Docker được thực hiện thành công trong quá trình xây dựng. Vấn đề là tôi muốn tải một số hình ảnh docker trong quá trình xây dựng để hệ thống bao gồm tất cả các hình ảnh cần thiết khi nó khởi động. Vấn đề là phần mềm KIWI sử dụng chroot để chạy các lệnh như tải docker, kéo docker. Các lệnh này cần một trình nền docker đang chạy. Khi tôi cố gắng khởi động deamon, nó luôn thất bại. Tôi đã thử những điều sau đây:

chạy docker qua: systemctl start docker thất bại (systemctl theo thiết kế sẽ từ chối bắt đầu một dịch vụ trong nhà tù chroot)

chạy docker qua: /usr/bin/dockerd cũng thất bại và tạo ra các bản ghi dưới đây

Có kỹ thuật nào để bắt đầu docker daemon trong nhà tù chroot không?
