Agreed. And some rc.d scripts are also overly verbose - starting a system with 150 virtual interfaces takes a significant amount of time via a serial console. > The hypothetical "average >user" probably wouldn't care if there were *no* kernel messages shown >on startup. Whilst they mightn't care about the current probe/attach messages, it is very reassuring for the kernel to show that it is actually doing something. > 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 Solaris is similar - leading to some nailchewing when rebooting after a change: Does nothing being reported on the console for 2 minutes mean that the kernel has gone off into limbo or it is just slowly grinding through *something*? Whilst SIGINFO helps once userland starts, I would not be comfortable with a system that reported nothing between the boot loader and login prompts. --=20 Peter Jeremy --vtzGhvizbBRQ85DL Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.12 (FreeBSD) iEYEARECAAYFAkqg5y8ACgkQ/opHv/APuIfr1QCbB1yDVhegaHupo3j9G0duznHR /uoAoIJKvXnuBtwXW0R5kFoT9dOSRMxV =SL8P -----END PGP SIGNATURE----- --vtzGhvizbBRQ85DL--
