+# This script is used for data collection for the bootchart boot

+# To profile the boot process, bootchartd should be called instead of

+# init=/sbin/bootchartd or rdinit=/sbin/bootchartd if you use an
+# initrd
+#
+# bootchartd will then start itself in background and exec /sbin/init
+# or /init in case of an inird (or an alternative init process if
+# specified using bootchart_init=)
