Comment # 2 on bug 1000440 from Michal Suchanek

It's nice that (some?) kernel messages are stored in /var/log/boot.msg

It does not fix the dmesg problem, however.

dmesg is the standard way to obtain recent kernel messages. If it does not
provide kernel messages it's broken. It's one place to look for the messages
regardless of being on the virtual console, serial console or logged in over
ssh on any Linux and BSD distro (including installers) I saw so far, except
SUSE.

You may very well have a logical reason to clear that buffer. That's moot. When
on every other system except Windows you get messages from dmesg you should get
them on SUSE as well.

It's same like making the start button red and stop button green when everyone
else does start button green and stop button red. There is logical reason to do
either but once vast majority of interfaces uses one way it is poor design to
do it the other way around.
