Hi All,
I am using Moblin 2 Beta image in Netbook platform. My requirement is to study
the boot time performance of moblin on Netbook platform.
I have a binary which will calculate the boot time with the following
requirements
1) I need to run that binary at the start up
2) I need to be a super user to run that binary
In windows I was able to calculate the boot time approximately by placing the
binary in the startup folder.
In Linux I tried by placing that binary in the /etc/rc.local script. But the
problem here was the binary was executed before the OS is completely loaded.
So I am not able to get the correct boot time in Linux. There is always
difference between boot time calculated with the stop clock timer and by that
binary.
Now I have following questions
* How to run a script automatically in Linux similar to windows startup? Or
How to calculate boot time in Linux?
* How to login automatically as a root user in Moblin?
Appreciate your help on this.
we have a tool called "bootchart" which gives you a much more detailed view of
boot time;
what you do is add "init=/sbin/bootchartd" on the kernel commandline in
grub.... and then you boot.
The PNG file with the graph will then be placed in the /var/log directory, and
will show what is done
during the various phases of the boot.
