Debcraft – Easiest way to modify and build Debian packages

The article touches upon an important point that applies to all complex (software/computer) and long-lived systems: "Too much outdated and inconsistent documentation (that makes learning the numerous tools needlessly hard.)"

The Debian Wiki is a great resource for many topics, but as with all documentation for very long-running projects - at least those that do big, "finished" releases from time to time - it seems tough to strike a balance between completeness and (temporal) relevance. Sure, in some weird edge case scenario, it might be helpful to know how this-and-that behaved or could be worked around in Debian 6 "Squeeze" in 2014, but information like that piling up also makes the article on the this-and-that subject VERY tedious to sift through if you are only interested in what's recent and relevant to Debian 12 "Bookworm" in 2025.

Most people contributing to documentation efforts (me included) seem very reluctant to throw out existing content in a wiki article, even though an argument could be made that the presence is sometimes objectively unhelpful for solving today's problems.

Maybe it would be worth a shot to fork the wiki (by copying all content and have a debian.wiki.org/6/ prefix for all things Squeeze, a /7/ for Wheey, a /12/ for bookworm, etc.) for each major release and encourage people to edit and extend release-specific pages with appropriate information, so readers and editors would have to "time-travel" through the project (anmd problem/solution) history in a more conscious and hopefully less confusing way, and make it easier for editors to prune information that's not just relevant for release N+1 any more.

I'm very open to learning more about anyone's thoughts on how to solve this well: How to keep documentation in "living documents", editable not only by a small group of contributors (like many projects to with mkdocs et al. as a replacement for an actual wiki), but also keep the "historic baggage" both easily discoverable (for when it's relevant and useful, because that does happen), yet not have it stand in the way of all those who will be confused and obstructed by its presence.

Something like this is probably a bigger deal than it should be. I keep a .deb of some scripts that I want on all my systems. Truly basic, it just puts the script in /usr/bin. It was quite hard to tell if I'm doing things the sane way and I ended up with the scripts in a few different places - if I look back over the folder I was using there seem to be 3x copies of everything from following what seemed to be a beginner tutorial.

It was a weird experience. Commands like `debuild -us -uc` are opaque about what the flags are supposed to be doing and the process did seem to be naive to the fact that I have a git repository over there and I want to check out a specific commit, maybe run some scripts to build artefacts and then map the artefacts to file system locations. Add some metadata about them along the way.

It quickly put me off packaging. It was much easier in the short term to just run a custom build script to copy everything to the correct location.

I can very much sympathise with the point here, at a previous company we used to use .deb packages for adding things to user's machines, and the Debian packaging tools were completely impenetrable for anyone not deeply immersed in the Debian way of doing things. We ended up with fpm to build packages because it just did what it was told. I would have liked something that didn't drag Ruby along with it, but never got to doing anything about that.

I suspect that debcraft still has far more Debian opinions than I would have wanted though. Mentions of sources, source packages and autopkgtests are the kinds of things I didn't want, I just wanted a package that put files on a system at locations I could specify. At that point containers are not needed either because you're just producing a file, not running a bunch of highly Debian specific commands.

I build the package contents with rpmbuild and create the .deb file with dpkg-deb. This allows me to use a single .spec file for both debian and redhat systems. It's still necessary to create the changelog and control file in exactly the right format to appease dpkg-deb, but it's easier than dealing with all the dh_ commands.

Just a reminder that it doesn't have to be this way, and the Debian problem is mostly self-inflicted and caused by decades of backwards compatibility. You don't have to suffer it if you control what's running on your machines.

Let's see how btop (mentioned in the article) is packaged by other distributions.

Alpine: one very transparent and easy to understand shell script with about 20 LOC:

https://gitlab.alpinelinux.org/alpine/aports/-/blob/master/c...

Arch: same thing (there are a couple more files there, one of them is for an optional new version checker, the other is automatically generated):

https://gitlab.archlinux.org/archlinux/packaging/packages/bt...

Void Linux: unlike the previous two, this uses a declarative language; it's still very short and easy to understand (though I prefer the imperative approach):

https://github.com/void-linux/void-packages/blob/master/srcp...

Chimera Linux: same as Void:

https://github.com/chimera-linux/cports/blob/master/user/bto...

I often write Alpine & Arch packages, and it's honestly a joy. For most programs it takes just a few minutes, how the result works is obvious to anybody even moderately familiar with Linux.

> Unlike how rpm or apk packages are done, the deb package sources by design avoid having one massive procedural packaging recipe.

I think that one massive recipe of a well documented preprocessed language such as RPM is exactly what makes RPM maintenance a breeze compared to DEB. The inputs and outputs of each stage are clear. The expansion of the macros. The idea that you only need to execute a single command `rpmbuild` and everything is neatly wrapped from underneath it.

This seems to be the thing: an ecosystem has a bad system (npm, pip, gem, deb stuff), someone decides the system is bad or has bad documentation, and writes some new tool (yarn, pipenv, debcraft), and that becomes the new standard for a while. Then 4-6 years later someone does the same thing again. When you return to the ecosystem after a while you find that there are three layers of outdated “new hotness” CADT you have to sift through.

Only Go did this right by getting the first-party tooling right from the outset (and then upgrading it, again first party, with modules). Nix seems to have come close but now there are Nix flakes which seem to be the same pattern.

It’s called “deb”. Debian should fix this. The fact that they’re spending their time removing version notices in xscreensaver and not fixing the basic tools and formats used is a mistake.

Not something I've used but I do enjoy these programs that make things that can be a pain in the ass slightly easier.

Could you explain the differences to tools like debspawn and the like ?
