Configfs

Configfs is a RAM-based virtual file system provided by the 2.6 Linux kernel.^[1]

Configfs appears similar to sysfs but they are in fact different and complementary. Configfs is for creating, managing and destroying kernel objects from user-space, and sysfs for viewing and manipulating objects from user-space which are created and destroyed by kernel space.^[2] It is typically mounted at /sys/kernel/config (or more rarely at /config).
