Still the link applies to debian as well, look for:
".deb based distro - Debian or Ubuntu Linux"
And i believe the manual steps at the bottom apply to linux in general

You have a debian/ubuntu like system.
Also you should always keep an old kernel in case you notice something broken on your new kernel.

Hi,
I am upgrading my machine with new version of os which have newer version of the kernel.
I have to remove my current kernel(which is going to be old kernel in next reboot) after up-gradation because i don't want to get prompt to choose the kernel at booting time.
I tried few methods:
1 . Try to remove using command ( sudo apt-get purge uname -r )
-- but after it gives a pop up (dialog box) to select yes or no.(But i don't to do that because system is automated, user should not interact with system).
My intention is remove to old kernel at very first time when it reboot(so no prompt will show to select the kernel by grub)..
Please if you have any best solution for this. please share.
Thanks
Anurudh

Anurudh,
In case your only concern is that you should not wait to make a choice of kernel at boot time then you can change the grub.conf file.
In case of older grub, on installing the new kernel the boot entry for it will be on the top.
So make "default=0" and "timeout=0" in your grub.conf file.
In case of grub-2,
You may need to do some more work through grub config files in /etc and then building new grub.cfg file through grub2-mkconfig command.
Another work-around is to remove all the initrd, System.map and vmlinuz files of unwanted kernels from the /boot location and rebuild grub.conf.
Hope this helps!
