Although, since graphics cards are probably always fixed PCI devices, maybe a limited form of `udevadm settle` (one that doesn't block the rest of boot process) would work? You can know when the *first* device has been detected. This is probably just as poor a suggestion as above, but worth a try: Add a dependency on dev-dri-card0.device (and an udev rule to apply TAG+="systemd" to drm devices). (Even crazier would be to allow BOINC to start as normal, but then *restart* it as soon as the first GPU driver has been loaded.) -- Mantas Mikulėnas
