DKconfig3 bool "/proc file system support" if EXPERT
12 It's totally cool; for example, "cat /proc/interrupts" gives
18 information about your system gathered from the /proc file system.
20 Before you can use the /proc file system, it has to be mounted,
22 That location should be /proc. A command such as "mount -t proc proc
23 /proc" or the equivalent line in /etc/fstab does the job.
25 The /proc file system is explained in the file
26 <file:Documentation/filesystems/proc.rst> and on the proc(5) manpage
27 ("man 5 proc").
