I apologize - I think that this might be a little off topic, but I know that a lot of you folks are Linux experts, and I was not sure where else to turn...
I am trying to learn more about kernel tuning. Right now, my specific question is "what does the command echo "4 4 1 4" > /proc/sys/kernel/printk do"? I understand that (a) it writes the values "4 4 1 4" (without the " marks) to the file /proc/sys/kernel/printk (b)which tunes certain kernel parameters, but I have no idea what parameters it is tuning. Having figured out this much, I have googled on Linux kernel tuning and found a lot of interesting articles on "how to tune parameter X"; however, I have not found a definitive reference on all (or at least most) of the tunable parameters and how to tune them. Rather than ask someone to "give me a fish" by explaining just what the .../printk file tunes, I thought I'd ask to be "taught how to fish", e.g. for someone to nudge, push, shove me in the right direction. Is there a definitive reference on kernel tuning, and would someone be so kind as to point me toward it? Feel free to use the clue-by-four if necessary, but please be gentle ;-).
