Or I’ve heard you could run it in a Docker container on a bigger machine
You can definitely run it in a VM (which is how I handle it) but container support wouldn’t surprise me.
The “silly” part was more that if you have x86 you can use opnsense/pfsense but I’m with you in that SQM is a big draw as well as less risk of compatibility issues as my APs are also flashed with openwrt. And the BSDs were well behind on wireguard support when I first switched to x86, although they have since caught up now I believe.
