Re: Kernel-option for quiet booting?

Well, the following patch to /usr/src/sys/kern/subr_prf.c works for me.
It's not a simple boot switch, but I ususally compile one kernel without
this patch and call it bsd.debug.  Then I can get the messages by choosing
to boot bsd.debug instead of the default bsd.

(Note that this kills *ALL* kernel messages to the console, not just
 the messages during the boot phase.)

If anyone has a better set of patches, I'd love to get a copy.
