This seems like an important distinction - the information which needs to be available with dmesg and the information best shown to the user at startup are not necessarily the same. The hypothetical "average user" probably wouldn't care if there were *no* kernel messages shown on startup. The Xubuntu box I'm writing this from shows only GRUB messages before the login prompt on tty1, and only service startup messages on tty8 (not to suggest that FreeBSD ought to be more like Ubuntu...). IOW, why bother painting it at all? Plain galvanized steel is very durable, and quite attractive when kept clean ;-) -James Butler
