# sddm-autologin-gate — ExecStartPre for sddm.service (one-shot autologin).
#
# A DeckShift session switch arms autologin right before restarting SDDM:
# gaming-session-switch writes the autologin drop-in AND touches the marker.
# This gate runs every time SDDM starts:
#   - marker present  -> a switch is in flight: consume the marker, keep the
#                        drop-in, SDDM autologins into the target session once;
#   - marker absent   -> cold boot / crash / manual restart: delete any stale
#                        drop-in so the normal password greeter shows.
# /run is tmpfs, so the marker can never survive a reboot.
