mkfs.cramfs

mkfs.cramfs is a command line tool used to format a filesystem in CramFS format. CramFS is a compressed read-only filesystem specifically designed for embedded systems. The tool allows users to create CramFS filesystem images which can be used to store and access files on embedded devices efficiently. When using mkfs.cramfs, users can specify various parameters such as the filesystem size, compression options, and block size to customize the resulting CramFS image. The tool comes pre-installed in many Linux distributions and can be invoked with specific options to create CramFS filesystems. After formatting, the generated CramFS image can be loaded onto a compatible device where it can be mounted and used as a read-only filesystem. Overall, mkfs.cramfs is a versatile and essential tool for creating and managing CramFS filesystems in embedded systems.
