--- title: "New APKBUILD: LLM edition" url: https://perrotta.dev/2026/02/new-apkbuild-llm-edition/ last_updated: 2026-02-18 --- **Problem statement**: package [`prek`](http://prek.j178.dev/) for [Alpine Linux](https://alpinelinux.org/). `prek` is a modern replacement for [`pre-commit`](https://pre-commit.com/), covered ([many times]({{< ref "/tags/pre-commit" >}})) in this blog[^2]. [Previously]({{< ref "2022-01-23-alpine-linux-new-apkbuild-workflow" >}}). It's already a breeze to create `APKBUILD`s. I've been doing so for ages. Now, in 2026, with agentic LLMs, it's even more so! I can be more useful to the Alpine Linux community by increasing my efficiency as a package maintainer. Yesterday I used [Amp Free](https://ampcode.com) in *smart* mode (Opus 4.6) to scaffold the `APKBUILD` for `prek`, using the [AUR `PKGBUILD`](https://aur.archlinux.org/packages/prek) as a baseline. Prompt: ``` write an APKBUILD for prek, inspired by https://aur.archlinux.org/packages/prek once written, copy it to knol (ssh knol) aports dir: ~/workspace/aports (in knol) ``` The result: ```shell # Maintainer: Thiago Perrotta <{redacted}> pkgname=pre pkgver=0.3.3 pkgrel=0 pkgdesc="Better pre-commit, re-engineered in Rust" url="https://github.com/j178/prek" arch="all" license="MIT" makedepends="cargo cargo-auditable" subpackages=" $pkgname-bash-completion $pkgname-fish-completion $pkgname-zsh-completion $pkgname-doc " source="$pkgname-$pkgver.tar.gz::https://github.com/j178/prek/archive/v$pkgver.tar.gz" options="net" # fetch dependencies prepare() { default_prepare cargo fetch --target="$CTARGET" --locked } build() { cargo auditable build --release --frozen target/release/prek util generate-shell-completion bash > $pkgname.bash target/release/prek util generate-shell-completion fish > $pkgname.fish target/release/prek util generate-shell-completion zsh > $pkgname.zsh } check() { cargo test --frozen cargo test --frozen -- --skip cache_gc_keeps_local_hook_env --skip cache_gc_removes_unreferenced_entries } package() { install -Dm755 target/release/$pkgname -t "$pkgdir"/usr/bin/ install -Dm644 $pkgname.bash "$pkgdir"/usr/share/bash-completion/completions/$pkgname install -Dm644 $pkgname.fish "$pkgdir"/usr/share/fish/vendor_completions.d/$pkgname.fish install -Dm644 $pkgname.zsh "$pkgdir"/usr/share/zsh/site-functions/_$pkgname install -Dm644 LICENSE -t "$pkgdir"/usr/share/licenses/$pkgname/ install -Dm644 README.md -t "$pkgdir"/usr/share/doc/$pkgname/ } sha512sums=" 87f5b5905d0c95b7f55a789eb00b463bb987c5fc981d83500f34a41b8e9ea2e4a0ac9d45a0c3a029a7957de33f5ade866c396c399252eb4a7a9e09e32e270b99 prek-0.3.3.tar.gz " ``` This was a great initial attempt, but [tests](https://gitlab.alpinelinux.org/thiagowfx/aports/-/jobs/2223891) failed: ``` Stopped on the first failure.

Then I got interrupted and the night ended. Today, I continued with [Claude Code](https://claude.com/product/claude-code).

I can't compile `prek` on my little alpine linux VPS (1GB RAM). Apparently Rust is a monster that requires a lot of RAM for compiling and linking software with hundreds of dependencies. I tested it by grabbing the built `.apk` package from the GitLab pipeline from my MR: ``` ⏺ x86_64 passed. Let's grab the artifact and install it: ⏺ Bash(ssh knol "curl -L -o /tmp/prek-x86_64.zip 'https://gitlab.alpinelinux.org/api/v4/projects/3998/jobs/2224483/artifacts' && cd /tmp && unzip -o prek-x86_64.zip &&…) ⎿ % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 0 0 0 0 0 0 0 0 0100 3.51M 100 3. … +19 lines (ctrl+o to expand) ⏺ Bash(ssh knol "sudo apk add --allow-untrusted /tmp/packages/testing/x86_64/prek-0.3.3-r0.apk && prek --version") ⎿ (1/1) Installing prek (0.3.3-r0) Executing busybox-1.37.0-r31.trigger OK: 1257.5 MiB in 579 packages prek 0.3.3 ⏺ Installed and working. prek 0.3.3 on knol. All 8 completed architectures passed (riscv64 is still building). ``` The LLM tries to use `sudo` instead of `doas`, which is not correct on Alpine Linux. It works anyway because I have the [`doas-sudo-shim`](https://pkgs.alpinelinux.org/package/edge/main/x86_64/doas-sudo-shim) package installed: ```shell % sudo -h Usage: sudo (-i | -s) [-n] [-u ] [ [--] [...]] sudo [-ins] [-u ] [--] [...] sudo [-h] Execute a command as another user using doas(1). This is not the original sudo, but the doas shim for sudo. It supports only a subset of the sudo options (both short and long) that have an equivalent in doas, plus option -i (--login). Refer to sudo(1) for more information. If you need some sudo features that are not supported in doas, replace package 'doas-sudo-shim' with 'sudo': apk add sudo !doas-sudo-shim.
