Verified live on a SteamOS 3.8.14→3.8.16 update: the A/B partset switch rebuilds /etc and drops everything not on Valve's keep list — the udev rule (uhid access: virtual pads silently degrade to Xbox 360), the vhci-hcd autoload (native Deck pad transport), and the UDP buffer sysctl (back to 208 KB → stutter). Valve's sanctioned extension point is a drop-in under /etc/atomic-update.conf.d/ — itself on the stock keep list, so it self-preserves. install.sh §4 and update.sh now register scripts/punktfunk-atomic-keep.conf there.
