# punktfunk — SteamOS atomic-update preserve list (drop-in for /etc/atomic-update.conf.d/). # # SteamOS's A/B updates rebuild /etc from scratch and carry over ONLY the files matched by # /usr/lib/rauc/atomic-update-keep.conf plus these operator drop-ins (the drop-in dir itself is # on Valve's keep list, so this file is self-preserving). Without it, every OS update silently # strips the host's system integration: /dev/uhid access (virtual pads degrade to Xbox 360), # the vhci-hcd autoload (no native Steam Deck pad), and the UDP buffer sizing (stream stutter). # Same wildcard rules as the stock list: '*' matches within a path segment, '**' across. ## Virtual-gamepad device access (uinput/uhid/vhci for the input group) /etc/udev/rules.d/60-punktfunk.rules ## vhci-hcd autoload (usbip transport for the native Steam Deck pad) /etc/modules-load.d/punktfunk.conf ## UDP socket buffer sizing (32 MB, matches the deb's sysctl drop-in) /etc/sysctl.d/99-punktfunk-net.conf
