找到解决方案了
目标国产系统核心包如下：
acl attr audit basesystem bash coreutils cpio cronie dhclient e2fsprogs filesystem glibc initscripts iproute iptables iptables-ipv6 iputils kbd ncurses openssh-server passwd policycoreutils procps rootfiles rpm rsyslog selinux-policy-targeted setup shadow-utils sudo usbtray util-linux-ng vim-minimal yum
经过精简的核心包如下：
basesystem bash coreutils filesystem iputils passwd procps rootfiles rpm shadow-utils vim-minimal yum
执行脚本：
bash <script_name> -g null -p basesystem bash coreutils filesystem iputils passwd procps rootfiles rpm shadow-utils vim-minimal yum
制作镜像的脚本如下：
- #!/usr/bin/env bash
- set -e
- usage() {
- cat <<EOOPTS
- $(basename $0) [OPTIONS] <name>
- OPTIONS:
- -p "<packages>" The list of packages to install in the container.
- The default is blank.
- -g "<groups>" The groups of packages to install in the container.
- The default is "Core".
- -y <yumconf> The path to the yum config to install packages from. The
- default is /etc/yum.conf for Centos/RHEL and /etc/dnf/dnf.conf for Fedora
- EOOPTS
- exit 1
- }
- # option defaults
- yum_config=/etc/yum.conf
- if [ -f /etc/dnf/dnf.conf ] && command -v dnf &> /dev/null; then
