This would already simplify the OpenWrt build system. That should be fine. OF will keep searching from first till last for a match. > What about the changed labels? Are they considered ABI too? You mean LED names. I would consider those ABI. People can have scripts which configure the LEDs how they want, blinking heartbeat, etc. > Regarding file names, I'm new to ABI policies.

I tftpboot it, grabbing both the kernel and the DB blob from my TFTP server. If the blob changes names, i would need to modify my uboot configuration. I don't know if Debian has full support for any of these boards, but if i remember correctly, flash-kernel has a database of machine names and DTB file names. My wrt1900ac is quite happy running Debian, but i don't have it booting the Debian way, because i use it for kernel hacking. But maybe there are people out there that do. Andrew
