(1) What are all these messages for?
Well, during bootup, the system does a number of things, and
whenever something is done, the system tells you about it. For
instance, rather early on in the boot process, the kernel tries to
probe the hardware installed. By closely watching these messages
(type `dmesg' to see them after the system has booted; they are
also in the file /var/log/messages) you can tell exactly what
happened. For instance, suppose the Ethernet card fails, then the
system will tell you about it.
Later on, a number of programs are started which provide certain
services. The system tells you about each process started, and it
emits an error message if that fails.
(2) How can I speed up booting?
For me, the longest time spent is waiting 15 seconds for the SCSI
devices to settle. You can configure the kernel to wait a shorter
time, but I tried it and found that I had to boot the system twice
with the shorter time.
What also takes time is probing for hardware. The `generic'
kernel includes support for a lot of hardware, you might want to
compile your own kernel with support for just those pieces you
actually have.
Starting all the daemons also takes time, you might want to turn
off the ones you don't need. See /etc/rc.conf or
/etc/defaults/rc.conf.
