This email is from a Debian maintainer, about Debian introducing a new hard dependency on Rust. It's not some random Rust advocate telling Debian folks that they should use Rust against their will.

Yes there are absolutely some obnoxious "you should rewrite this in Rust" folks out there, but this is not a case of that.

[richard_todd]

There are like 1000 Debian maintainers, right? This person doesn't speak for the project as a whole, and as far as I can tell he is telling Debian folks they will be accepting rust whether they want it or not, and whether their preferred architecture is supported or not. Maybe there was some organizational vote on this, but if so it isn't referenced in the thread. It says "I plan", not "Debian decided to".

And regardless, my point is it would be more sensible to say "I'm going to introduce an oxidized fork of apt and a method to use it as your system apt if you prefer" and then over the next year or so he could say "look at all these great benefits!" (if there are any). At that point, the community could decide that the rust version should become the default because it is so much better/safer/"modern"/whatever.

You seem to think of "rust enthusiasts" as some organized group with a goal of writing Rust for the sake of it. Rust is long past such extremely early adopter phase.

What you're seeing now is developers who are interested in writing a better version of whatever they're already working on, and they're choosing Rust to do it. It's not a group "Rust enthusiasts" ninjas infiltrating projects. It's more and more developers everywhere adopting Rust as a tool to get their job done, not to play language wars.

[richard_todd]

Nah, I called out redox and another commenter pointed out ripgrep as an even better example of what I’d prefer to see, and those are also by what I would call rust enthusiasts. I don’t think of them as a monolithic group.

Where we disagree is I would not call injecting rust into an established project “writing a better version”. I would love it if they did write a better version, so we could witness its advantages before switching to it.

They are referring to adopting the Sequoia PGP library, which is written in Rust. There are plenty of benefits to using Sequoia which you can investigate now, no need to theoretically wait for the integration to happen. Not coincidentally, the RPM package manager also adopted Sequoia PGP.

[richard_todd]

First off, the mail references far more rust adoption than just Sequoia, but since you bring it up: here is how RPM adopted Sequoia in Fedora-land. There was a proposal, a discussion with developers about the ramifications (including discussion about making sure the RPMs built on all architectures), and there were votes and approvals. Costs and benefits and alternatives were analyzed. Here's a page that has links to the various votes and discussion: https://fedoraproject.org/wiki/Changes/RpmSequoia

Can't you see how much more thought and care went into this, than is on display in this Debian email (the "if your architecture is not supported in 6 months then your port is dead" email)?

[dralley]

> (including discussion about making sure the RPMs built on all architectures)

All officially supported ones. The Debian discussion is not about officially supported Debian ports, it's about unofficial ones.

That's not how open source software development works.

I wasn't asked by Linus whether ipchains should become the default over ipfirewall nor whether iptables should become over ipchains.

I wasn't asked whether GCC should use C++ instead of C as the language to build GCC itself.

I can go on with lots of examples.

Why should APT be different and require the maintainers to fork their own project do introduce changes? Why should an undefined "community" (who is that? apparently not the APT developers...) decide? Does this have to be done for every code change in APT?

[richard_todd]

ipchains is a perfect representation of what I want to see. They introduced it as an option alongside ipfirewall in 2.1, made it the default but allowed fallback to ipfirewall in 2.2, and removed ipfirewall in 2.4. That is a sane way to introduce a large breaking change. Not to mention they provided compatibility scripts to try to smooth over the user-side differences.

They certainly did NOT say "I'm replacing ipfirewall with ipchains in six months, and if your distro can't handle it you should sunset your distro."

It shouldn't be controversial to request a measured approach when making major changes to software lots of people depend on. That's part of the burden of working on important software. Note I'm not against apt or anything moving to rust.

edit: spelling

[throwaway7356]

Ah, so the same that seems to be happening here? As https://lists.debian.org/debian-devel/2025/10/msg00288.html says Rust is already a requirement on all but four architectures:

> Rust is already a hard requirement on all Debian release architectures and ports except for alpha, hppa, m68k, and sh4 (which do not provide sqv).

And just like with the kernel the fallback gets removed eventually.

[richard_todd]

If you think a situation where everyone had access to ipchains for 3 years to figure out how to migrate is similar to a situation where some architectures will be killed in six months without ever having had access to the new product then I don't know how to help you. What can affected ports do? Implementing a toolchain backend is a tall order.

We didn't talk about your gcc-to-c++ example, but if you read up on it you will know they took the pulse of affected developers, started experimental branches, made presentations, and made sure no architectures were left behind. All of which this Debian developer is failing to do.

Look I don't even disagree with the ultimate result... I don't think Debian needs to indefinitely support every strange port it has built up over the years. The way it's being done, though, doesn't sit right. There are far more mature ways to steer a big ship. Your own examples are showing the way.
