Best Cross-Distro Installation Tools for Linux?

swillden asks: "I need to package up some commercial Linux software for multiple distributions (Red Hat Enterprise 3 and 4, Fedora, Novell Desktop, SuSE Professional and Enterprise, Mandrake and Debian), and I'm wondering what tools others have found useful. The software is closed source and needs to be very easy to install. This has been an ongoing problem for commercial software on Linux for some time. Has there been any progress?" "So far, the options I'm looking into are:

1. Create distribution-specific packages using each distribution's tools. Nice in lots of ways, but a lot of work for ~11 different distributions.
2. Use a commercial cross-distro installer like InstallShield. This is what the previous developers chose.
3. Use one of the open source cross-distro installers, like autopackage or Loki.
4. Write a custom installer.

I really would like to provide distro-specific packages, to make use of the native dependency management solutions and to make the software fit nicely into each system, but implementing, testing and supporting all of those installers may be too costly. It may also exclude any other Linux distributions unnecessarily.

I don't like the current InstallShield installer for multiple reasons. First, it's written in Java which is fine except that it can only run if a JRE is present. Requiring users to install a JRE so they can run the installer to install a (non-Java) product is really annoying. Also, it doesn't really know how to do any proper dependency management, so the developers had to take the approach of installing everything that might be required, often duplicating tools that might already be on the system, and sometimes even creating conflicts. Obviously this approach doesn't integrate with the native package management at all.

The Loki installer has some of the same limitations as InstallShield, but it doesn't require Java and it's very scriptable, so I could probably write code to do the dependency checking and be smarter about what to install.

Autopackage looks very interesting, and I'm going to take all of the docs with me to read on a flight this afternoon. However, I'm concerned that it may be unstable, as it's just reached a 1.0 release.

Finally, I could always just write an installer from scratch, but that may be even more work than creating all the distro-specific packages."

loki_setup...

...has been working great for me, for several commercial games like Unreal Tournament 2004. Over the past five years, I've shipped several products using it, both on commercial CDs and downloadable installers.

It _is_ a little quirky in some regards, but once you get it working, it pretty much works everywhere.

If you use it, please use our codefork at http://icculus.org/loki_setup/, since the Loki Games version died with Loki, and we've put several man months of further development into it since (largely improving things as we ship new software with previously unexpected requirements, a MacOS X port, more archive formats and other enhancements). We're pretty fast to respond when someone has a bug, too.

Otherwise, I'd say give people a tarball and let them sort it out. :) Yes, trying to make distro-specific packages is SO BAD as to make this a better option...even between the various RPM-based distros.

Someone DID mention that it's nice to enable those distros to repackage it in their preferred format, if there's a want, and I think that's an interesting idea as long as you don't rely on people to show up and do it. Gentoo, for instance, provides their own packages for most of the games I've shipped, which will even extract the data off the retail CDs if need be, etc...this empowers Gentoo users to have a consistent experience, but they can still use my loki_setup based installer if they want, as can those without a "real" distro package. This seems to be the least-messy solution at the moment, and it allows the distro maintainers to compete on features while you maintain a single, decent and universal solution yourself.

At least, this works well for me. Your mileage may vary.
