Installation Modification

[farjibaba]

Dear Friend

I want to modify the Installation procedure of Kubuntu 12.04. When we Install Kubuntu in hard disk a dialog comes which asks us about the
"Key Bord Layout, Time zone, HDD Partition etc..." and we carry on next next next...... thats the location I want to modify this thing like say

when it say welcome to Kubuntu 12.04 and other things like when I ask about the keybord layout there should be only one option.

I am taking the ISO with Remastersis and there is no option to modify that thing I have change the splash screen in remaster sis..

My moto is that i have modified the kubuntu and now i m taking backup with remasther sis as a distribution but at the time of installation I don't want the text "Kubuntu 12.04"

how can i do this or is there any method in ubuntu like RHEL the kick start insatllation

If you want to put a current install on multiple computers quickly then "dd" is the only way to do it.

Sorry

I didnot understand "dd" please elaborate it ;..

If you want to put a current install on multiple computers quickly then "dd" is the only way to do it.

I can think of a few disadvantages to this.

• Volume and partition UUIDs won't change. While this doesn't technically "break" anything, it does mean that multiple, distinct computers will have the same UUIDs on their partitions and volumes.
• A dd-ed boot volume won't boot on a UEFI-based machine without also adding the necessary NVRAM variable.
• Configuration files that contain machine-unique tokes like hostnames or static IP addresses will have to be modified.
• ...probably more...

@farjbaba: Mind telling us a little more about your motivations? What problem are you trying to solve?

All valid. I just remember using dd to install quickly on 5 computers once and although there was some post install modification (all I can remember was changing the host name right now), I just felt the whole process was a ton faster. If he can tell us his exact requirements then we might be able to better recommend a solution.

I'll grant you that it's fast! I have often used dd to move an existing installation onto a new hard drive. Fabulous tool. You can increase the speed of it by setting the block size equal to the cache size of your drive. I usually use bs=16M on the dd line.

Setting the block size to the cache size is something many people forget and that's why they think its deadly slow. I usually pipe dd through "pv" so that I can gauge my progress, makes it a whole lot more fun to use dd rather than just guessing at your progress.

Yep, but try that when you're dd-ing between two SSDs. You'll find the double-pipe slows things considerably. So you have to go the more primitive route: open a second console window, find the PID for dd, and send it a SIGUSR1.

You have two SSDs! What type of sorcery allows you to afford two? Jokes aside, I will keep that in mind next time I use it between two SSDs. I use dd extensively as a back-up tool since it is so flexible and still so bulletproof. dd combined with pigz (parallel gzip) and you have one of the best back-up solutions known to man. Unfortunately it is an image so its not incremental.

No sorcery whatsoever. Just made some good friends in the IT department where I work. Soemtimes little goodies then just magically fall out of the sky.
