multiple quirks

[mcandre]

• ./setup.sh && ./scripts/feeds update packages triggers errors with openwrt/sdk:x86-64-24.10.5: gpg: can't open '/builder/keys/*.asc': No such file or directory, error: RPC failed; curl 18 transfer closed with outstanding read data remaining, /builder/staging_dir/host/bin/find: 'feeds/packages': No such file or directory
• The various openwrt images all target the linux/amd64 buildx platform. Would love to see buildx images published to target more of the architectures that OpenWrt supports.

What is this ./scripts/feeds business? Can that be used to bootstrap a conventional opkg environment? Or did the opkg installer die?
