+- The scrollback buffer of the standard VGA console is located in

+-
+- This feature might break your tool of choice to flush the scrollback
+- buffer, e.g. clear(1) will work fine but Debian's clear_console(1)
+- will be broken, which might cause security issues.
+- You can use the escape sequence \e[3J instead if this feature is
