I'm currently on a linux machine and want to explain to a class of mine the boot process in depth. I understand it quite well, but wanted to show them how things are handled as the system boots (I'm using Red Hat). So for example, I wanted to show them all the messages that appear when the system boots, not just the contents of dmesg. I want to show them lines such as:
and then the rc.sysinit part:
Welcome to Red Hat ....[Press I to enter interactive ...]
However, since these are not displayed is dmesg and they go off the screen, I'm not sure how I can get some type of file with all the content that is displayed to the screen. Any ideas? Thanks for your time.
