> Like, there is no auto-update story, but at the same time it is a giant (relative to what it should be, IMO) Linux distro full of vulnerability-laden components. This space is in dire need of a minimal security-from-the-ground-up alternative with a real trustworthy update story.
I admit I'm not super deeply familiar, but I would have guessed the opposite - that openwrt had no extra software included, not least because it's targeting devices where total disk and RAM are measured in megabytes. What components would you remove/replace that make it "giant"?
The only thing that can reasonably be called "giant" about OpenWRT is the package repository: it has a decent package manager like you'd expect to find on a desktop Linux distro, and it can be used to add functionality to your router, including a fair bit if stuff that goes well beyond what is typically used on routers. But the default install set is not giant, and is typical of what you'd expect for a wireless router.
