SubjectRe: Boot messages
From
Date
As long as we're on this topic, I'd like to make a semi-related
suggestion. One of the small items that I miss from NetBSD/FreeBSD is
the consistent format of the device probe messages. When you boot the
system, each driver should print its probe status message in the same
format, and present the same information. Right now each author has
chosen his or her own format, and the result is an ugly hodge-podge of
messages when the system boots. This also makes it more difficult to
spot a certain message when they're all flying by at boot time.

Here's a sample bootup sequence from a NetBSD/Alpha machine, to
demonstrate what I'm talking about. With this format, it's pretty
easy to just watch the beginning of each line for a specific device
when the system is booting.

Is it appropriate to mention that the TCP/IP implementation is by the
Swansea University Computer Society, or that Donald Becker wrote the
WD8003 driver? This just makes Linux look like more of a patchwork
than it already is, rather than giving a seamless, well-integrated
appearance.
