使用devmaster替换udev启动

使用devmaster替换sysmaster虚拟机启动场景的udev，使得虚拟机启动后可以正常激活逻辑卷、挂载分区、加载网络等等。

在sysmaster源码根目录下执行如下命令进行安装：

# sh -x tools/run_with_devmaster/install_devmaster.sh [debug|release]

测试环境

  • 测试的虚拟机环境如下：
# uname -a
Linux localhost.localdomain 5.10.0-60.18.0.50.oe2203.x86_64 #1 SMP Wed Mar 30 03:12:24 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
  • devmaster的规则直接取自虚拟机环境中的udev规则，在此基础上对sysmaster环境中不支持的规则进行了适配。引用的规则以及适配情况见规则清单和适配差异。

安装方法

  1. 参考sysmaster虚拟机启动方案搭建启动环境。

  2. 安装devmaster的二进制以及相关配置文件，在sysmaster源码根目录下执行如下命令：

# sh -x tools/run_with_devmaster/install_devmaster.sh [debug|release]
  1. 重启系统，选择sysmaster启动项。进入主系统后检查devmaster服务状态和网络连通情况。

systemd相关命令无法在sysmaster启动环境中使用，使用到这些命令的规则需要进行适配。部分适配动作会对功能造成影响，比如注释某条规则。某些适配动作不影响功能，但会产生行为差异，比如规则中调用systemd-run <cmd>命令会生成一个systemd的服务并执行cmd命令，适配后会去除systemd-run前缀，直接由devmaster创建子进程来执行cmd。另外清理了规则中的一些语法告警，比如IMPORT{}类规则使用了赋值操作符等，此类修改不影响规则执行结果。
