Good. I like to have my Linux system reboot as infequently as possible (ie
a week is too short an uptime), but when it does it's nice to see all the
nice features of your various hardware being identified. What is annoying
you? If your logfiles get too big, process and erase the useless bits once
in a while.

No. Unless you have the sense to run sysklogd. Or use the 'dmesg'
command. The buffer for kernel messages can be increased if you have >4k
of messages upon bootup (or is the ring bufer more than 4k in recent
kernels anyway?)

How are people supposed to see their hardware identified correctly if
messages are cryptic? Give a good reason why verbose messages are a bad
thing, and I might have sympathy!
