NetBSD beast 6.99.7 NetBSD 6.99.7 (LOCKDEBUG) #59: Mon Jun 4 13:15:47 EST 2012 build@beast:/usr/src/sys/arch/i386/compile/obj/LOCKDEBUG i386
I like the splash screen feature and I boot silently to suppress kernel boot up messages, but I would also like to see kernel messages once booted up.
Boot up silently (-z) and you then have no way to get kernel messages back on the console.
I patched init_sysctl.c to add a sysctl to alter boothowto to change kernel message verbosity from 0 silent to 4 debug.
