## Introduction<a name="section469617221261"></a>
The init\_lite module starts system service processes from the time the kernel loads the first user-space process to the time the first application is started. In addition to loading key system processes, the module needs to configure their permissions during the startup and keep the specified process alive after sub-processes are started. If a process exits abnormally, the module needs to restart it, and to perform system reset for a special process.

## Constraints<a name="section12212842173518"></a>
Currently, the init\_lite module applies only to small-system devices \(reference memory ≥ 1 MB\), for example, Hi3516D V300 and Hi3518E V300.
## Usage<a name="section837771600"></a>
init divides the system startup into three phases:
pre-init: operations required before system services are started, for example, mounting a file system, creating a folder, and modifying permissions
init: operations required for starting system services.
post-init: operations required after system services are started.
In the **init.cfg** file, each of the preceding phases is represented by a job, which corresponds to a command set. The init\_lite module initializes the system by executing the commands in each job in sequence. Jobs are executed in the following sequence: pre-init \> init \> post-init. All jobs are stored in the **jobs** array in the **init.cfg** file.
In addition to the **jobs** array, the **init.cfg** file also provides a **services** array, which is used to store the names, executable file paths, permissions, and other attribute information of the key system services that need to be started by the init process.
The file is stored in **/vendor/hisilicon/hispark\_aries/init\_configs/** under **/etc/**. It is in JSON format, and its size cannot exceed 100 KB.
The format and content of the **init.cfg** file are as follows:
```
{
"jobs" : [{
"name" : "pre-init",
"cmds" : [
"mkdir /testdir",
"chmod 0700 /testdir",
"chown 99 99 /testdir",
"mkdir /testdir2",
"mount vfat /dev/mmcblk0p0 /testdir2 noexec nosuid"
]
}, {
"name" : "init",
"cmds" : [
"start service1",
"start service2"
]
}, {
"name" : "post-init",
"cmds" : []
}
],

"uid" : 1,
"gid" : 1,
"once" : 0,
"importance" : 1,

A single job can hold a maximum of 30 commands \(only **start**, **mkdir**, **chmod**, **chown**, **mount**, and **loadcfg** are supported currently\). The command name and parameters \(128 bytes or less\) must be separated by only one space.

## 简介<a name="section469617221261"></a>
init组件负责处理从内核加载第一个用户态进程开始，到第一个应用程序启动之间的系统服务进程启动过程。启动恢复子系统除负责加载各系统关键进程之外，还需在启动的同时设置其对应权限，并在子进程启动后对指定进程实行保活（若进程意外退出要重新启动），对于特殊进程意外退出时，启动恢复子系统还要执行系统复位操作。

## 使用说明<a name="section837771600"></a>
init将系统启动分为三个阶段：
“pre-init”阶段：启动系统服务之前需要先执行的操作，例如挂载文件系统、创建文件夹、修改权限等
“init”阶段：系统服务启动阶段
“post-init”阶段：系统服务启动完后还需要执行的操作
上述每个阶段在配置文件init.cfg中都用一个job表示，每个job都对应一个命令集合，init通过依次执行每个job中的命令来完成系统初始化。job执行顺序：先执行“pre-init”，再执行“init”，最后执行“post-init”，所有job都集中放在init.cfg的jobs数组中。
除上述jobs数组之外，init.cfg中还有一个services数组，用于存放所有需要由init进程启动的系统关键服务的服务名、可执行文件路径、权限和其他属性信息。
配置文件init.cfg位于代码仓库/vendor/hisilicon/hispark\_aries/init\_configs/目录，部署在/etc/下，采用json格式，文件大小目前限制在100KB以内。
配置文件格式和内容说明如下所示：
```

"jobs" : [{
"name" : "pre-init",
"cmds" : [
"mkdir /testdir",
"chmod 0700 /testdir",
"chown 99 99 /testdir",
"mkdir /testdir2",
"mount vfat /dev/mmcblk0p0 /testdir2 noexec nosuid"
]
}, {
"name" : "init",
"cmds" : [
"start service1",
"start service2"
]
}, {
"name" : "post-init",
"cmds" : []
}

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
