In addition to the trust factor, what happens when this service dies? Netboot.me offered essentially the same service years ago, but disappeared and stopped working, with many guides written for and around their service.
It uses IPFS gateway setup in local network, this enables: * Caching of downloaded data (this is useful when using it to boot multiple computers in one LAN) * More trust: boot menu is served from local IPFS gateway using immutable hashes. It is also really easy to review it by hand. * It's a bit more service-dies-scenario proof
Downsides include lack of better documentation and messy code in places - it's a large scale refactor that changes the basics of how the tool works and isn't quite polished. It lives at https://netboot.devtty.eu/. There is no set-up instructions(tr;dr setup: run lan-open ipfs gateway, add A dns record 'ipfs.local' pointing at it in your lan DNS server, rest like netboot.xyz).
