, and wait for bootchart to appear. You'll now have three bootcharts. One is without ureadahead, one is when ureadahead is profiling, and the final one is with ureadahead behaving normally. File a bug report on ureadahead (Ubuntu-bug ureadahead) and attach these three files along with the output of "sudo ureadahead-dump" (this is quite a bit, so capture it in a file ). I'll take a look, and we'll see if we can fix that bug for you! Ureadahead exits with status 4! This isn' t actually a bug Statu

-user mode of the graphic interface. 6: restart. You cannot set the default running level to 0. Otherwise, the system will be restarted. Most linux systems use a mechanism called System V to start the running level, while ubuntu uses upstart instead of init to start the System process. So there is no inittab file to change the default running level. The default run-level file for ubuntu is/etc/init/rc-sysinit.conf. Method of success: Method 1: (kernel

Here's a cure for the upstart: PAfter using the simple factory model, now the upstart just need to sit in the car and say to the driver: "Drive" on it. To see how this is achieved:Abstract Product Rolespublic interface car{public void Drive
