debian boot hide all messages
Solution 1:
Consider installing plymouth, it is a graphical boot menu, hiding all details, requires kms though
Solution 2:
You may have to do this the long way.... For each script in /etc/init.d that's loaded at your runlevel, find the 'start' section and for each call to 'log_msg' or equivalent add '>/dev/null 2>&1' to the end of the line. This will stop the messages at start up but it may not be the most elegant solution. diJenerate
