AutoPackaging for Linux

Isak Savo writes "The next generation packaging format for Linux has reached 1.0. With Autopackage officially declared stable, there is now an easy way for developers to create up to date, easy installable packages. There are lots of screenshots available including a flash demo of a package installation."

The purpose of autopackage

[FooBarWidget]

No doubt lots of people will have all kinds of questions about autopackage, such as:
- "What idiots!! Another packaging format is the last thing we need!"
- "What's wrong with apt-get?"
- "Everybody should use Gentoo!"

Slashdotters are highly encouraged to read the autopackage FAQ! Our project has existed for over 2 years now, and many people have asked us those questions. In short: autopackage is not meant to replace RPM/DEB/apt-get/etc.

If you have more questions, feel free to come over at #autopackage at irc.freenode.net
We'll be glad to answer your questions

Why bother?

# What's wrong with centralized repositories, apt style?

The system of attempting to package everything the user of the distro might ever want is not scalable. By not scalable, we mean the way in which packages are created and stored in a central location, usually by separate people to those who made the software in the first place. There are several problems with this approach:

• Centralisation introduces lag between upstream releases and actually being able to install them, sometimes measured in months or years.
• Packaging as separate from development tends to introduce obscure bugs caused by packagers not always fully understanding what it is they're packaging. It makes no more sense than UI design or artwork being done by the distribution.
• Distro developers end up duplicating effort on a massive scale. 20 distros == the same software packaged 20 times == 20 times the chance a user will receive a buggy package. Broken packages are not rare: see Wine, which has a huge number of incorrect packages in circulation, Mono which suffers from undesired distro packaging, etc
• apt et al require extremely well controlled repos, otherwise they can get confused and ask users to provide solutions manually : this requires an understanding of the technology we can't expect users to have.
• Very hard to avoid the "shopping mall" type user interface, at which point choice becomes unmanagably large: see Synaptic for a pathological example of this. Better UIs are possible but you're covering up a programmatic model which doesn't match the user model esp for migrants.
• Pushes the "appliance" line of thinking, where a distro is not a platform on which third parties can build with a strong commitment to stability but merely an appliance: a collection of bits that happen to work together but may not tomorrow: you can use what's on the CDs but extend or modify it and you void the warranty. Appliance distros have their place: live demo CDs, router distros, maybe even server distros, but not desktops. To compete with Windows for mindshare and acceptance we must be a platform.

# What's wrong with NeXT/MacOSX style appfolders?

One of the more memorable features of NeXT based systems like MacOS X or GNUstep is that applications do not have installers, but are contained within a single "appfolder", a special type of directory that contains everything the application needs. To install apps, you just drag them into a special Applications folder. To uninstall, drag them to the trash can. This is a beguilingly easy way of managing software, and it's a common conception that Linux should also adopt this mechanism. I'd like to explain why this isn't the approach that autopackage takes to software management.

The first reason is the lack of dependency management. Because you are simply moving folders around, there is no logic involved so you cannot check for your apps dependencies. Most operating systems are made up of many different components, that work together to make the computer work. Linux is no different, but due to the way in which it was developed, Linux has far more components and is far more "pluggable" than most other platforms. As such, the number of discrete components that must be managed is huge. Linux is different to what came before not only in this respect, but also because virtually all the components are freely available on the internet. Because of this, software often has large numbers of dependencies which must be satisfied for it to work correctly. Even simple programs often make use of many shar

I have to say this is like a godsave for linux. Most layusers will want some easy installation like this instead of using something like Yum (even if it is a GUI front-end to yum like GYUM). This is one giant step towards a viable desktop linux - and I believe that it isn't a replacement for apt/yum/[INSERT YOUR FLAVOR HERE] but uses them under the hood.

Before everyone starts bashing it and says that apt or emerge or whatever they use is the way to go, seriously think about it - one click installation, from a FRIENDLY user-interface, and easy to manage system for installing and uninstalling programs. Now if this were part of the base install on many distributions and some sort of standard was established (seriously, we need standards) I can probably convince my scared-of-Linux-because-it-is-hardcore friends to actually try Linux out.
