In embedded arm development, when making the root file system with BusyBox, one of the directories that must be built is the/dev directory. This directory is important to all users because the directory contains all the external devices used in all Linux systems, that is, all the device nodes. When building the/dev directory, there are two approaches: static build and Mdev Device management tool building.

Introduced/ dev/shm/ is a device that uses the Tmpfs file system, which is actually a special file system. the default size in Redhat is half of physical memory, so that time is not mkfs formatted. TMPFS is a memory-based virtual file system on the Linux/unix system .TMPFS can use your memory or swap partition to store the file ( that is, its storage space in virtual memory , the VM consists of real memory and swap ). Thus, TMPFS primarily stores s
