Could you be a little more specific please cause I don't understand?

The problem in my case is that when I execute the above, I get: cat: can't open '/sys/devices/system/clocksource/clocksource0/current_clocksource': No such file or directory In general, my /sys directory is empty. This file should exist to my filesystem prior to kernel execution or should it be created by the kernel when it starts executing; but for some reason it is not being created in my case?
Thanks.
