BcoreOS实战：用一个升级包，让Rocky Linux跑进Ubuntu服务器

GitHub – acode001/BcoreOS: BcoreOS是一个跨系统发行版的升级方案，支持内核、驱动、库、应用程序整体打包，批量差分升级 · GitHub

一、在Rocky10.1（BcoreOS将其定义为系统母盘）上制作升级包

1、查看系统母盘的内核校验和，如：4070e7f10398bb2e4688ba1d9a877519

md5sum /boot/vmlinuz-$(uname -r)

2、根据内核校验和下载对应的AOS ,下载最新版本aos-6.225.2474-202608271637-4070e7f10398bb2e4688ba1d9a877519-6.12.0-124.8.1.el10_1.x86_64-ext2-ape-x86-64-vda.img.gz

3、在母盘系统内创建aos目录并拷贝BcoreOS_build.sh和下载的aos-*到aos目录下;

4、运行BcoreOS_build.sh脚本。

[root@localhost aos]# chmod 555 ./BcoreOS_build.sh
[root@localhost aos]# ./BcoreOS_build.sh
Available AOS versions for BcoreOS(/boot/vmlinuz-6.12.0-124.8.1.el10_1.x86_64):
