+# Save splash profile information during boot? If set to 'yes', a record
+# of the boot-up sequence will be kept in /lib/splash/cache/profile. The
+# profile file is useful for debugging purposes and for replaying the

+# down the boot, so don't activate it if you don't plan to use it.

+# Which console mode to use for the silent splash. Valid values are:
+# text,graphics. If 'text' is selected, the splash tty will be treated
+# just like any other tty by the kernel. With the 'graphics' option,
+# the kernel will not touch the tty in any way. 'graphics' could be
