Strongly agreed. I'd rather be running a Debian, with systemd, and boring regular utilities, than the bespoke environment openwrt has crafted together.

I'm super glad openwrt exists, and their uci config predates systemd's attempt to build a cohesive consistent whole system configuration pattern & is epic, but given the capabilities of these systems it feels so worthwhile to de-specialize the environment, to make it more boring.

What I really want is Kubernetes oriented tools that can manage hostapd & something like dawn or openert's usteer for band/ap steering. And some other ancillary wifi tools. Maybe maybe a setup for radius/enterprise, instead of just psk. You can do so much more with it, but at its core openwrt is 90% packaging for openwrt. It's not even particularly super well tuned hostapd: theres so much wireless config one can go try & enable that really is just additional 802.11 specs hostapd supports, they may improve your openwrt wifi experience.

I agree. I tried running OpenWrt as a wired router on an x86 mini PC, and found that it had some really powerful features and was certainly rock solid as a router. But there were some major annoyances, too. For example, their documentation includes a script for expanding the root filesystem [1] that left my system unable to boot. And while I didn't use it long enough to make it through an upgrade, their documentation on upgrades makes the process sound very brittle (it sounded like configs for installed packages don't carry over by default) and confusing.

I thought about trying to set up an Ubuntu (or other popular distro) box as a router, which I think would be much easier to maintain over time. But my concern is that I might overlook some important config that is set by default in OpenWrt, and leave my machine vulnerable to attack. Having a web UI that I can log into and view/make config changes is also kind of nice. Are there any good out-of-the-box solutions or guides for doing this? (I know that OPNSense/PFSense are really popular among homelab users, but unfortunately the Marvell NICs in my mini PC are not supported in FreeBSD).

I have been doing this myself recently. The docs around this are pretty out of date. The docs as they’re written only work for the ext4 images if I remember correctly. I got it to work with the squashfs version, but it was really janky. The problem is the OS just writes the to the empty space at the end of the squash partition without changing the partition table. I could only successfully get it working if resized the partition on first boot before the writable overlay is created.

I feel similarly about the process. There is either a command or a place on disk where you can put files to protect them across upgrades, but I can’t remember just now. I think it works that way because it’s targeted at embedded devices where I would think you typically bake everything you need into the root file system at compile time. I’m not an embedded engineer so maybe there are better ways of doing it.

I was using an ext4 image and still ran into problems. And in addition to the scripts on the page that I linked above, I also tried this other variation from their docs [1]. They all ended up rendering the sytem unbootable.

Eventually I think I ended up using an Ubuntu Live ISO to boot the system and made the change there. Definitely a bit of a pain, and according to the docs it sounds like something I would need to do again after an upgrade.

I also tried following their steps for "building your own image with larger partition size" [2], but couldn't get that to work either.

I had fun playing around with OpenWrt. But in the end was forced to admit that I didn't really need any features in OpenWrt, and whatever benefits I was getting from it were not worth the effort. Also, even a minute of downtime for a reboot was pretty annoying to my family when they were trying to stream a movie, etc.

I know the answer to this. The ext4 filesystem that openwrt creates by default is just janky. To get well-working filesystem that you can resize etc, you need to build custom image with a small patch to fix up the ext4 fs creation.

This is exactly the sort of thing why I'd want a openwrt for "big" devices. But I should get that patch also merged upstream...

Yup, that's the answer. Debian is rock solid, and a script with a bunch of iptables and iproute2 commands is so much simpler than the mess that is OpenWRT's network setup. I only use it for dumb APs, and even then it's questionable -- the UI is nice, but configuring it is unnecessarily complex IMHO.
