Looking at internal/commands/install.go, it only installs new packages, but doesn't uninstall removed ones. That's the biggest benefit of Brew bundle gone.
BTW how much of it is vibe coded?
apk uses a similar approach by default, and I think it's a wonderful way for a package manager to operate.
Basically, /etc/apk/world keeps a list of explicitly installed packages.
When you manually install a package, it's added to this list, when you manually remove a package, it's removed from the list.
Installation and upgrading (and "fixing) merely ensures that those packages and their dependencies are installed, no more, no less. This also automatically cleans up stale, unused dependencies.
It's a lovely way to get deterministic results. You can just back-up that world file, or copy it to another machine and get the exact same installation.
aconfmgr[https://github.com/CyberShadow/aconfmgr] is a kinda similar project for pacman-based distributions.
The difference is that it strives to track all non-user files, (not just packages, and especially /etc), but you can adopt it partially.
So, this is better than `dpkg --get-selections/--set-selections`? Oh, because it's partial?
Big fan! Was like magic at first but now I have a big bunch of Aptfiles to deal with instead... Currently working on solving that with the next-generation tool apt-bundle-bunch, which has a simple declarative format to manage your apt-bundle projects in an Aptbundlefile. It's already great for agents and Im working with Claude on a curl|sh install for the v1.
I hate the Aptfile format after looking at it.
The ppa directive hints that this is intended for Ubuntu because otherwise installing PPAs is a great way to break a non Ubuntu distro.
The deb directive uses the old and soon to be deprecated .list file extension. DEB822 format is the replacement.
The key directive adds the key as globally trusted for all repos instead of locking it to a specific repo as recommended by Debian. I think this is required under the new DEB822 repo format.
This appears to be a Show HN.
Put in my mise.toml :)

Brew got one thing right that no Linux package manager seems to emulate: it doesn't require root for normal operations and even goes so far as to error out if running as root (https://docs.brew.sh/FAQ#why-does-homebrew-say-sudo-is-bad).
