可选：永久开机挂载（写入 /etc/fstab）

脚本末尾追加这段：

# 开机自动挂载
grep -q "${MOUNT_POINT}" /etc/fstab || echo "${ISO_FILE} ${MOUNT_POINT} iso9660 defaults 0 0" >> /etc/fstab
echoInfo "已配置/etc/fstab，重启自动挂载离线源"

回滚恢复脚本 restore_kylin_sp3.sh

#!/bin/bash
if [ $UID -ne 0 ];then echo "需要root权限";exit;fi
umount /os/kylinsp3
rm -f /etc/yum.repos.d/Kylin-SP3-Local.repo
mv /etc/yum.repos.d/bak/*.repo /etc/yum.repos.d/ 2>/dev/null
yum clean all && yum makecache
echo "✅ 已还原麒麟原始yum源"

使用步骤

chmod +x build_kylin_sp3_arm64.sh
bash build_kylin_sp3_arm64.sh

SP3 注意点
