I have a network of very nearly identical Dell XPS 13 laptops that I manage with a script. The master pushes the contents of its filesystem to the others so I only have to manage one system. It's worked really well over several years. I just got a new Dell XPS 13 to serve as the master and there have been some changes that were difficult to integrate with the network (high-res screen, /dev/sda replaced with /dev/nvme0n0) but those problems are fixed thanks to you guys.
Now I'm running into "trap invalid opcode" errors on the older systems. Can I disable some of the newer CPU instruction sets on the master laptop when compiling to hopefully generate binaries that will work on the older systems? If so, could anyone point me in the right direction? I don't want to use distcc please. CHOST="x86_64-pc-linux-gnu" CFLAGS="-march=native -O2 -pipe -fomit-frame-pointer" - Grant
