Configfs

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

Details

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. It is typically mounted at /sys/kernel/config (or more rarely at /config).
