+Kernel: skip export start in krt_init_scan() when gr_wait is set
+
+When graceful restart recovery is active (-R), krt_start() sets gr_wait=1
+on the kernel channel to defer export until recovery completes (via
+graceful_recovery_done()). However, krt_init_scan() unconditionally calls
+channel_start_export() when transitioning from KPS_INIT, without checking
+gr_wait. When graceful_recovery_done() later runs, it finds gr_wait=1 and
+tries to start the export again, triggering:
+
+  bug("%s.%s: Attempted to start channel's already started export")
+
+Reported on bird-users by Christoph (Jan 2026) for BIRD 3.1.5.
+Still present in 3.2.0 despite bda2178e ("Kernel: pause exports also
+on restart until scan is done") which set rt_notify=NULL in krt_start()
+but didn't address the krt_init_scan() path.
+
+Skip channel_start_export() in krt_init_scan() when gr_wait is set,
+letting graceful_recovery_done() handle it instead.
