Debain

In the Meilix code repository you find a metapackage named meilix-default-settings which contains custom settings in directories as debian, etc, and user. In these directories one can make changes to make them be included in the build ISO. As Meilix runs on Debian we package our custom user settings in a Debian package to be installed along all the other software packages. The process and utility to make a Debian package is called debuild.

Directories in the meilix-default-settings:

What is debuilding?

It’s Debian slang for “making a deb package” and that stirred quite some confusion in our communications. Debuild is actually a rebuilding of the metapackage. But as to rebuild the Debian package you usually type debuild -uc -us therefore I stick to the language

Suppose someone has edited a configuration file in the metapackage according to its desires to achieve a specific result in the ISO it won’t get in unless he rebuilds the metapackage.He has not only to edit the metapackage but also to rebuild it to get the desired output in the ISO. To make the process automated, we have made a tiny script which will debuild the metapackages during each and every build, we only need to modify the metapackage.

Actually the first meilix-default-settings folder is the only metapackage and inside of it is the sub-metapackage which is responsible to get the changes applied in the ISO. To see a change in the ISO, we only need to edit the meilix-default-settings usr or etc folder in the first layer. Then, we need to debuild the metapackages.

Code-Base:

This file is present here

1. #!/bin/bash
2. rm meilix-default-settings_*                                    
3. cd meilix-default-settings                                      
4. debuild -uc -us

Let’s go through the whole code base line by line:
Line 2 deletes the previous meilix-default-settings binary packages.
Line 3 in this we changed our directory to the metapackage folder that is of our concern.
Line 4 is the most important line, it builds the whole metapackage and brings back all the binary packages and metapackages after making the desired changes.

Follow the example below to know that actually how it works:

This pull request is responsible to turn off system sounds by default in the generated ISO. Pull Requests files in which I only edited the this file and rest of the files get changes in the process of debuilding the metapackage (ignore .travis.yml file).
