In addition to /proc, the kernel exports
information to the /sys virtual file system
(sysfs). Programs such as the dynamic device
manager, udev, use /sys to
access device and device driver information. The implementation of
/sys has helped to tidy up the
/proc file system as most hardware information
has been moved to /sys.
/sys exposes kernel data structures and
control points, which implies that it might contain circular
references, where a directory links to an ancestor directory. As
a result, a find command used on
/sys might never terminate.
