specific applications. For applications such as industrial control that do not need to update control programs frequently, it is sufficient to select a read-only file system such as caramfs, in addition, the cramfs compression rate is as high as 50%, which can greatly save our storage space. However, for applications that need to store data such as data collection, read-only file systems cannot meet the needs of application systems, we can choose a readable file system like jffs or yaffs.

In addition, it can also automatically delete the corresponding device file nodes under/dev after the device is uninstalled (this is useful for some hot swapping devices and is automatically created when plugged in, is automatically deleted when unplugging ). Another advantage is that when writing a

ARM-Linux transplantation (III)-init process Startup Process Analysis K-style Reprinted please indicate from Hengyang Normal College 08 electric 2 k-style http://blog.csdn.net/ayangke,QQ:843308498 mailbox: yangkeemail@qq.com We usually use busybox to build the necessary applications for the root file system. Busybox determines the operation to be performed by passing in parameters. When the INIT process s

In fact, the root secrets are all in the SU program, the android root permission Cracking Analysis describes that the default su program of the Android system can run only root and shell, which is safe. If you remove this restriction, it is root cracking! Next, we will analyze how the program obtains the root permission. If you are familiar with the Linux su command, y
