The thing is I oftentimes need to have it already in kernel by default and when I need it there is no way to install anything (i.e. non-working network), almost nothing installed, using less is a complete hell in these situations. Screen is very impractical for me to use, same with tmux. Kmscon isn't even in my distro (and the kmscon's idea isnt pretty at all - running a terminal right on top of another one just because we lost essential feature). Besides that it is needed when experiencing and dealing with bugs, system is locked up and i need to see the on-screen output - i.e. critical situations [yes this happened to me more than once in near past]. Thank you for tip and link!
