Precisely. /proc and /sys are created by the Linux kernel before
userspace represented by 'Pid Eins" even starts. /proc and /sys are
'virtual filesystems' that the kernel employs to communicate to
userspace.
I know it is very basic question for linux programmer, but please give
me
some answer about this.
You figured it out yourself: good work. For authoritative info, look at
https://www.kernel.org/doc/Documentation/filesystems/
under proc.txt and sysfs.txt.
