+# Systemd name of DRM device to have weston/agl-compositor startup depend
+# upon, if required.  Currently only x86-64 seems to need a dependency to
+# avoid failures due to racing with i915 driver init on e.g. UpSquared.
+# It seems safer for now to only apply it there rather than doing a blanket
+# default everywhere that might then need to be over-ridden for vendor BSPs.
