Bug#600959: boot warnings too fast to read and not saved in any file nor dmesg
I'm quite distressed that again I am seeing warnings at boot that fly
off the screen and cannot be found in any log files.
I believe the message was similar to
udevd: GOTO 'acl_end' has no matching label in: '/lib/udev/rules.d/70-acl.rules'
But that is not important. What is important is that it is not saved in
dmesg, or anywhere else.
How can an administrator deal with warnings that fly past too fast and
are not even in the record that one can ShiftPgUp to on the console, as
that gets truncated during some kind of screen reset upon boot.
You might think that the messages were saved in /var/log/boot, however
the top of that starts only at "Activating swap...done"
One might think that running "Debian GNU/Linux, with Linux 2.6.32-5-686
(recovery mode)" might show more, but same problem: boot messages
truncated... can't see them in any file. And with recovery mode, one
will not notice any problem, as there are too many messages to be able
to notice the error messages anyway.
