This article mainly introduces how to use Ubuntu Imager to create an exclusive Ubuntu Live CD, which has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand.

Why customize Ubuntu Live CD?

In order to cater to the needs of different users and cover users more widely, Ubuntu has launched many versions of derivatives. However, it is difficult to adjust, the official version can not meet the needs of all users, we usually choose the most matching version and customize the system. If we can customize our own Ubuntu Live CD according to our hardware environment and software requirements, it will be convenient and personalized if we can install it and use it directly.

Distroshare.com is a website dedicated to helping users create their own personalized Ubuntu. Using the tools they provide, the process will be very simple.

Distroshare Ubuntu Imager script

There was a tool called remastersys that could help us create Live CD, and the project has been out of development for a long time. Fortunately, distroshare.com has developed a Distroshare Ubuntu Imager (Bash) script that can help us automate most of the process of Ubuntu Live CD creation, and we can create our own Ubuntu Live CD with only a few edits and execution of the script configuration.

Distroshare Ubuntu Imager is hosted on GitHub, and we can download it back using the following command:

Cd / tmp/wget https://codeload.github.com/Distroshare/distroshare-ubuntu-imager/zip/master

Then use the following command to extract it:

Mv master distroshare-ubuntu-imager-master.zipunzip distroshare-ubuntu-imager-master.zip-d / tmp/folder

Modify the configuration file

After unzipping, we need to modify the distroshare-ubuntu-imager.config configuration file as needed so that we can create an exclusive Ubuntu Live CD that meets our requirements.

After browsing to the unzipped directory, we can see two main files:

◆ distroshare-ubuntu-imager.config: customizing the configuration file for Live CD

◆ distroshare-ubuntu-imager.sh: automated scripts for generating custom images

You can use vi or nano to modify the distroshare-ubuntu-imager.config configuration file, in which the various configuration options are actually very clear, the official provides very detailed and good annotation information.

The GTK option defines whether to install GTK or Qt, which can be changed to NO if not installed.

GTK= "YES"

WORK defines the working directory of the script and the resulting ISO storage directory.

WORK= "/ tmp/folder"

You can change it to YES if you need to support EFI.

EFI= "YES"

By default, the script creates the Live CD with the Kernel version currently used by the system. If you want to specify the kernel version, you can change the following configuration:

KERNEL_VERSION= "specify kernel version number"

The official notes have been written very clearly, so I will not introduce them one by one.

Execute script

Sudo. / distroshare-ubuntu-imager.sh

After executing the packaging script, it automatically reads the configuration file we just changed and creates the necessary directories, cleans up the temporary files and compresses the packaged ISO file after automatically processing all configurations.

Create a boot flash drive

After the ISO image is generated, we can carve it to a CD, use it on a virtual machine, or run it directly from grub. Of course, we can also use the following command to write it to a U disk to boot:

Dd if=live-cd.iso of=/dev/sdX bs=1M

/ dev/sdX is your USB drive path.
