Start the shell at tty8 as login shell

[lslezak]

Problem

• The root shell running at tty8 does not set some default environment values like $PAGER.

Solution

• Start the shell as login shell to load the /etc/profile file
• That sets $PAGER to less and allows displaying ANSI colors, enable line wrapping by setting the $LESS options

Testing

• Tested manually
