Software Management
In any operating system, we need to install some software that will help us to do our day-to-day work. For example, if you are writing scripts, the stock software or application that comes with the operating system might not be enough. In that case, you need to install software such as Visual Studio Code to make your work easier. Likewise, in a corporate environment, you might need to add new software or even update existing software to meet your business requirements.
In the old days, installing software was a matter of extracting an archive to a filesystem. There were several problems associated with this approach, however:
- It was difficult to remove the software if the files were copied into directories also used by other software.
- It was difficult to upgrade software; maybe the files were still in use, or they were renamed for whatever reason.
- It was difficult to handle shared libraries.
That's why Linux distributions invented...
