Tools for creating a custom Linux OS based on Ubuntu

in flag
Shimanta Das

I want to create a new OS which is based on Ubuntu. I changed everything in Ubuntu like name, screenfetch logo, etc., but I failed when it comes to creating an iso for my OS. I want to change everything like bootloader logo, bootloader name, etc. I don't want to show any Ubuntu name in that. I also want to change the grub screen. Which tools/packages do I need to install for that?

In particular I want to know which tools are generally used by Lubuntu/Xubuntu teams when they make their OS from an Ubuntu build.

You should read this before creating another OS. https://itsfoss.com/desktop-linux-torvalds/

Lubuntu & [official Ubuntu flavors](https://ubuntu.com/download/flavours) don't create our own ISOs, they are built by Ubuntu infrastructure. I can provide links to the Lubuntu infrastructure, but it only deals with code, CI, testing etc. as the building of ISOs is performed on Ubuntu infrastructure. The same applies to all *flavors*. Ubuntu wiki pages document how Ubuntu ISOs are built.

FYI: I'd start by reading a blog from someone who did it, eg. I remember reading & appreciated the writings of the Jacquees ??? who does Makulu. He blogged about what tool he used, then forked & released his version used by himself in creating Makulu Linux when it was switched from Debian base to Ubuntu base many years ago (I used to read his stuff on g+; it was a little before g+ disappeared but g+ links were just elsewhere)..

The tool *currently* used by Lubuntu is https://phab.lubuntu.me/ (*you'll have to be quick to see it; we're currently moving our infrastructure and its being replaced!*) though of course most of use text editors (`vim` seems to be preferred) and commands to build & upload packages - as builds as already stated are done for all *flavors* by Ubuntu infrastructure just as with Ubuntu ISOs. We don't change any graphic/name, we have our own package which contains what we want which is seeded on the ISO (https://git.launchpad.net/~lubuntu-dev/ubuntu-seeds/+git/lubuntu)

My prior comment should also have included https://phab.lubuntu.me/w/release-team/iso-building/ as well as the global link I used

I changed everything in Ubuntu like name, screenfetch logo, etc., but I failed when it comes to creating an iso for my OS.

Modify the Pretty Name Variable in /usr/lib/os-release and change "Ubuntu" to the name you prefer. For changing the icon, run:

sudo cp -r /usr/share/icons/hicolor/256x256/apps/ubuntu-logo-icon.png /usr/share/icons/hicolor/256x256/apps/ubuntu-logo-icon.png.bak

And then place the logo's .png file in /usr/share/icons/hicolor/256x256/apps/ and rename the .png file to ubuntu-logo-icon.png.

I want to change everything like bootloader logo .

I assume you are talking about the boot splash screen, right? See How do I change the plymouth bootscreen? You can get one Plymouth them from Pling or create your own theme.

, bootloader name, etc. I don't want to show any Ubuntu name in that

See How to safely change OS name in grub boot menu? You have to modify /etc/default/grub.

Which tools/packages do I need to install for that?

A.F.A.I.K, there is no such tool/package.

I also want to change the grub screen.

I presume you're talking about the Grub theme. You can select one theme from Pling or create your own theme.

In particular I want to know which tools are generally used by Lubuntu/Xubuntu teams when they make their OS from an Ubuntu build.

They don't really use any tool, they modify the files and repositories themself.

You can use ```cubic``` to manipulate iso-files. Add/remove kernel-features and programs. Or you can do things to your excisting OS, like I think your doing given the useful answer by Someone (+ for Someone) and make an iso with ```ISO Master```.

I think that the reviewers missed the target by closing this question as "needs to be more focused", so I voted to reopen it. Also please review my edit to the question. If you think my edit needs improvement please improve it.

I'd recommend Cubic but you have to still go around and change branding, make your own DE, etc. I recommend building the desktop and server versions on Ubuntu Server with Cubic, it gets rid of those pesky DE bits scattered everywhere.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
