动机:
我想要一个完全模拟 Raspbian Buster 操作系统的容器化开发环境。就使用 Node.js 开发我们的客户端/服务器软件而言,我已经准备好了 - 但我们的最终产品依赖于 SystemD 服务,如果不需要启动 Pi 就可以在我自己的笔记本电脑上舒适地开发这些服务连接到触摸屏或 VNC 服务器等。
背景(带有重现步骤):
我正在使用以下 shell 脚本构建一个容器,其中包含使用 qemu-arm-static 修改的最新 Raspbian 发行版,以在 x86-64 机器上模拟 armv7l:
#!/bin/bash
#
# Modified script
# Original by jguiraudet
# Create a podman image raspbian distribution image for raspberry-pi
#
# Change the SRC path if needed:
SRC=https://downloads.raspberrypi.org/raspbian_full_latest
set -e
sudo echo Info: Need root access to mount the image to extract the content
mkdir raspbian-tmp
cd raspbian-tmp
echo Download image...
wget --trust-server-names $SRC
unzip *.zip && rm *.zip
DISK_IMG=$(ls *.img | sed 's/.img$//')
OFFSET=$(fdisk -lu $DISK_IMG.img | sed -n "s/\(^[^ ]*img2\)\s*\([0-9]*\)\s*\([0-9]*\)\s*\([0-9]*\).*/\2/p")
mkdir root
sudo mount -o loop,offset=$(($OFFSET * 512)) $DISK_IMG.img root
# Disable preloaded shared library to get everything including networking to work on x86
sudo mv root/etc/ld.so.preload root/etc/ld.so.preload.bak
# Copy qemu-arm-static in the image be able to interpret arm elf on x86
if /usr/bin/qemu-arm-static -version | grep 4.2.0; then
# Fix crash with `tcg.c:1693: tcg fatal error` by using a more recent version
wget https://github.com/multiarch/qemu-user-static/releases/download/v4.2.0-4/qemu-arm-static
chmod 755 ./qemu-arm-static
sudo cp ./qemu-arm-static root/usr/bin
else
sudo cp /usr/bin/qemu-arm-static root/usr/bin
fi
# Create podman images
cd root
sudo tar -c . | sudo podman import - localhost/spidercatnat/raspbian-full-for-x86_64:podman
cd ..
# Clean-up
sudo umount root
rmdir root
rm $DISK_IMG.img
sudo podman images | grep raspbian
我想在这个容器中运行 systemd,遇到了 podman(以前使用 Docker)。尝试运行容器podman run -ti --rm localhost/spidercatnat/raspbian-full-for-x86_64:podman /sbin/init
失败,即使以 root 身份运行:

我不明白为什么会发生这种情况或如何进一步追踪此错误。为什么投反对票?如何在启用 systemd 的情况下运行此映像?
