Dear all,
I read some articles about initrd, but how to view this process in my computer :(?
Is there anyway to display to the screen or write to the log file?
What did you read about initrd? Did none of these articles mention that it's not a process, but a preliminary filesystem image that is only used until the root partition becomes available? As soon as that step is reached it's no used by the system until the next reboot.
Dear pludi
Maybe my explanation is not clear enough
I mean, how can I view when initrd is initialized? What happens in this time?
You can view messages from the kernel using dmesg . These may or may not contain information about initrd. But basically there's not much happening: the kernel reads the file provided at the command line, unpacks it, and runs the init binary contained within.
The only way I can think of to get more information would be to attach to a kernel debugger interface, if present.
