There are many apps in ubuntu like vino, vinagre etc that sit idle on my PC and have no use. Removing these apps does not remove the dependencies and hence take up space. This space is costlier when I have to run the system live for recovery or some other works. Installing apps over the LiveRUN takes up space in RAM Drive. Hence I want to start from the kernel and build up ubuntu (for every LTS version) that will have all the features of the OS but will remove the apps I never need to use along with their dependencies, Hence providing me a light distro customized for me entirely.
I have previously heard of MinimalCD for Ubuntu but have never used. Is that what is to be used for this kind of a project?
