No, I don't mean the messages from the init scripts (I guess you can use the VERBOSE variable in /etc/default/rcS for that); I mean the bootup messages from the _kernel_, the ones you can read again with dmsg.
I searched the file /usr/src/linux/Documentation/kernel-parameters.txt and the BootPrompt-HOWTO, but I'm still not sure how to do this. Would you set the console kernel parameter to /dev/null or is that too drastic? Maybe /dev/ttyS0? I guess what I really want is something like "dmesg -n 1" to be applied during bootup time. Can I specify "console_loglevel" as a kernel argument? It's mentioned in the HOWTO but not in kernel-parameters.txt. TIA, Jose PD: If you wonder why I want this: I have some machines which dual-boot on an automatic schedule between Linux and NT, and they do so via LILO _and_ Linux. I just don't want the people using NT to realize that they're being booted for a couple of seconds into Linux before they're really booted into NT.
