Point-and-klik Linux Software Installation? 212

Posted by michael from the easy-as-pie dept.
bfree writes "While you may have come across klik before, you might not be aware of some of the major changes which have been taking place over the last few months. If you visit the old klik site you will see a link to the Next Generation klik, which aims to provide a web interface to install the entire collection of Debian packages, letting you grab any package from sid (and its dependencies) and 'install' it into its own location, similar to the system outlined in this recent slashdot story." See below for more on klik.

bfree continues: This is not the only change in klik recently however, now applications are built into compressed image (cmg) files rather then stored as application directories. This means that you can store the application on any filesystem and move it around at will. Klik no longer totally depends on kde. Where previously klik could only be used with konqueror, now you can also use firefox and elinks, and where previously kdialog was required, now any of dialog|Xdialog|kdialog should work.

Klik now also supports more distributions fully. The officially supported list of distributions is now Knoppix (3.7), Kanotix (BHX), Linspire 5.0 and Simply Mepis (2004.04). Klik assumes that you will have installed at least the lowest version of any package which is present in all supported distributions and build the applications as such. If a package you want klik to install depends on a package in this base system it will not be included in the cmg so you must have it installed or add it to the cmg by hand afterwards. If you want to try using klik on another distribution, your results will primarily depend on whether or not your distribution has the packages the cmg depends on and assumes are present. So you will certainly fail to install kde applications on a distribution with no kde (as all the supported distributions have kde), but programs with simpler, or less common and therefore missing from some supported distributions, dependencies can work just fine.

One of the best ways to demonstrate the power of klik's techiniques is with the Christmas present from probono, an OpenOffice.org cmg for version 1.9.65. With this cmg (which runs on far more distributions then klik's supported list, especially as it uses Linux transparent iso compression rather then cramfs) you can download one 100M file to try out the preview release of Ooo, no need to upgrade any parts of your system and if the system has been setup by root to use cmg files there is also no need to even be root. I think this demonstrates the very best feature of bundled applications, you can try a potentially reckless preview release of software without having to upgrade your system.

      This is actually a much harder problem that you might think. There are a few different solutions. The Windows solution has been a combination of trying to bolt down a core set of libraries that everyone can be expected to have, and generally completely ignoring dependencies/shared libraries and letting the installers either trample each other, or install multiple versions of the same thing in different places. It kind of works, but does have drawbacks.

      On Linux you could effectively do this by just having all packages statically linked, or have each package bundle up its own versions of all the libraries it will ever need. Neither is a very efficient solution for either disk space, or more importantly RAM (which is where shared libraries really start to earn their keep). The problem is partly that open source has a release early, release often approach, which means the base set of libraries (which Microsoft simply bolts down) tends to be an ever moving target (Microsoft simply does everything in huge upgrade jumps every now and then instead... except for a few things like DirectX). The other half of the problem is that with all that source code out there being shared freely there's an awful lot more code reuse and a much broader range of shared libraries and hence dependencies. This is a good thing most of the time, but causes issues for installing software.

      Linux got around these dependency issues by having distributions which package up all the dependencies for you. This works very well, especially with apt, apt-rpm, yum, portage, and all the other fun dependency resolving tools, but has one drawback: If you aren't installing a distribution provided package the system has a lot more trouble tracking (and especially resolving) your dependencies. That means installing and maintaining a Linux system is easy, but adding new software from third parties can be a pain in the ass. Debian and Gentoo attempt to solve this dilemma by havign so many packages available from the distribution that you don't want for anything. As well as this works, it again isn't quite a complete solution.

      Which finally brings us around to the open source attempts to try and provide systems to allow third parties to package software. The principle now is: You let the distribution do the hard yards of installing and maintaining the syste with their packaging and dependency resolving systems, and simply provide some distribution neutral package format that can still slot in amongst all of this. There are several solutions, each taking a slightly different approach such as ZeroInstall [zero-install.org] and Autopackage [autopackage.org]. They are still in the works, but look to have some surprisingly good solutions. They are definitely worth a look.

      So, in summary, Windows manages to have their system by:
      (1) Locking you down on base libraries, and having a slow upgrade cycle on those.
      (2) Windows developers not sharing as much code, and not caring about actually sharing libraries even when they do.

      That is a perfectly valid solution, and it does work, but its never going to fit with open source, which has a pretty fast developing set of base libraries (which is a good thing), a lot more emphasis on code sharing, and an eye for efficiency. That doesn't mean open source can't have easy to install software (it already does for anything distribution packaged, and various solutions for third party software are well on the way), merely that, because of some fundamental philosophic tenets of open source, it is a harder problem than on Windows, and requires more cunning solutions.

        Actually it is more like a base API, the various libraries constantly go through upgrades and such, more of a feature lock.

        On one hand this is a bad thing, Windows did not even have a (decent!) built in dearchiver until Windows XP, but on the other hand it is also a good thing, as the free market allowed a number of competing (and ultimately superior) archival formats to come forth and not have to fight against any one single OS-supported format.

        • Neither is a very efficient solution for either disk space, or more importantly RAM (which is where shared libraries really start to earn their keep).


        A key question becomes, on client workstations, are shared libraries REALLY all that much more efficient, a good trade off for the hassle that they cause?

        Honestly, a good HTML renderer, sure, Windows software has found a million and one ways to make use of that (A good portion of Visual Studio.NET's UI is basically a fancy IE window from what I can figure out, at least it behaves like one!), and other things like built in sound and video acceleration are (of course) handy to have around, but honestly, how often is some huge shared library really going to be used?

        Lets see, if I have a 3D modeling app open, Winamp playing tunes in the background, and my browser of choice (Firefox or IE which ever) up and running, what use are shared libraries to me?

        The UI, sure, but Windows has that, granted the options kind of blow, Win32 or .NET (suck up programmer time or suck up system resources), HTML renderer? Got that, my 3D program in the least is going to be using it for its help system and likely also for parts of its UI.

        A standard image manipulation library? If I install a new image manipulation program I want something revolutionary, something different, from it. Heck, $400+ painting programs sell specifically because the programmers have developed some kick'in libraries that are limited just to that program. Besides, I don't want a shared library that specializes in doing a Physics Simulation of paint on paper!

        Games? Sure, to some extent I guess, but how many games am I going to be having running at once? Honestly? 2 tops, even that is rare, most likely, just, well, 1.

        On server and application server environments, shared libraries are a blessing, but for a client environment, flexibility and the capability to rapidly deploy applications to the end user seems to be higher priority.
        • OK, any modern OS uses shared libraries and this is a good thing. Let's take that as axiomatic. There are a few people around who believe that shared libraries are inherantly evil and should go, but they apparently don't know anything about operating system engineering. Clearly if they did, they would not say that.

          So like any powerful tool, there is a tendency to overuse it, or use it where it's not appropriate. Without shared libraries we could not have systems like Windows XP, Linux or MacOS X because n

    • I don't think that dependencies are handled very well in apt-get, rpm, etc. All too often, by installing one 100K package, you wind up installing 1GB of dependencies. As far as I can tell, there's no alternative except for the override in rpm. I think the next generation installer is going to present a graphic dependency map showing you why the dependencies might be needed and let you determine which ones you are going to install.

      BTM
      • Dependencies are dependencies - they exist to say "I NEED these things to even work at all." If you find some package that lists something as a dependency but you have no problems using the package without it, you've just found a bug.

          • I'm talking about the scenario where package a uses icons from package b

            What package does that? If package b includes some files that are commonly used by other packages, those files should be packaged separately in, say b-common. Debian has lots of *-common packages.

            If it's just a few icons, another alternative would be to simply ask the person who packages a to include those icons in a (renamed or in another directory, so a doesn't conflict with b).

      • Uh. Why would you want to install a package without the other packages which DEPEND on it? Apt (at least) does install a conservative number of dependencies, and presents you with a list of recommended packages (if any are optional).

If you are on a supported distro they should not be a problem, if you are not on a supported distro then you may not have required libraries.

    I have read through the docs, but I can't find any indication of how klik really works. Clearly the cmg file has to be mounted somewhere. I found references to the overlay file system (which linus refuses to integrate). Does the cmg file get mounted somehow (with a root helper) and overlayed on the root file system? cmg files seem to be created from binary deb files, so I don't imagine they are recompiled to look for their files elsewhere (say $HOME/etc or something).

    I believe this klik system could have real application across all kinds of distros, even RPM-based. However klik still doesn't truely offer (due to how linux works) apps that are dependency free. For example the galeon.cmg would still require mozilla and a few other things. I suppose they could make each cmg independent, but then we'd have tons of glibc's in memory, plus multiple copies of gtk, etc. How do they get around this issue?

Config files can be copied to /etc if you so wish and snap with files destined for /var (you are prompted to copy either if they are present). Besides, klik is run as a user, and needs no root privileges (except for the presence of suitable mount points in fstab).

    Looking at the documentation, I'd say this is a step in the right direction for Linux to be appropriate for home users. For the typical user, it is important that they can find an "application link" somewhere on the internet and just click it to use it. Package management systems like apt/urpm/emerge work well and are still necessary for Linux, but klik-style installation will enable average users to be comfortable using software that hasn't already been installed by someone else. As a result, they will probably feel a lot more "at ease and in control" during their Linux experience.

    As a bonus, the linked application only runs with the user's privilege level. That means if it's a malicious app, it won't hose the whole system, and security/recovery becomes much easier.

    It almost makes me want to try out desktop Linux again (using OS X right now).

  • To be a fully usable system for 'home' users it needs root access so it can install spyware etc. It also needs to be able to hide some file somewhere to implement those 30-day trial counters.
