HOWTO debug Ubuntu boot hang
HI guys,
I've got a version of Ubuntu 13.10 in my Virtualbox OSE virtual computer. It hangs very early in the boot. GRUB runs and the boot starts.
In /var/log/boot.log, I see the same messages as I see on the screen. I have to press ESC to see the text while the computer boots. There are perhaps 3 or 4 "Starting <service>....OK" messages, and that is all. I never get a chance to log in.
The problem I have is that I don't know in which order the boot scripts are supposed to run. With the "old" initscripts, one would see Snn<script> or Knn<script> and the "nn" would be the number representing the order in which the scripts are "S"tarted or "K"illed. That isn't the case here.
I've found the boot scripts in /etc/init/*.conf so I can match boot messages to scripts.
However, I'm unable to determine which script got stuck since I don't know the order of execution. My version of 13.10 is customized, not stock, so I can't compare to a known good.
Any ideas would be greatly appreciated.
Thanks!
Andy
