Usability of Command Line Interfaces
Something really astonishing about Ubuntu (and all Debian distributions) is the state of the Command Line Interfaces to the package management system.
First, there is "dpkg", coming in several incarnations (20 different programs). This is not supposed to be used by actual humans, and there are good reasons for that, it's just unusable. Then there is apt (9 different programs) providing something somewhat usable. With package management, I have 4 main things I usually want to do:
- Install a package
- Remove a package
- Upgrade all packages
- Find out information on installed packages
Speaking of Gentoo, the whole init/rc system of Debian/Ubuntu is also a huge step backwards from Gentoos rc system. The command line tools are obscure, the user has to specify the start order manually where this could be specified by package maintainers. In Gentoo there are runlevels which have clear, understandable names and a tool that manages all the dependencies for you. Instead of pondering when to start which service in what order, and especially when to stop them again, you simply state that you'd like to have service x running at runlevel y, or not. While there is somewhat of a GUI for that in Ubuntu, it doesn't seem to work all too often and it doesn't include many of the services.
This was pretty surprising to me, as I figured that Debian was the system used by many administrators and they'd probably care about such things. Strange.
