This is because UNIX serial devices come with lots and lots and lots of built-in software features. Have you ever hit ctrl-C to kill a stuck program? The serial port, even an emulated one in a GUI, does that directly. It has a "send SIGINT when you hit this key" setting.

I am sorry for being blunt first of all. But what you said makes absolutely no sense to me. Why would a terminal need a serial port to function ? Also I have used the terminal in both Debian and Fedora distributions. I have never made any connection to any serial port before using them !
Why would I need to do so ? OSes like Windows also offer ctrl+c combination to kill the program(not that I like comparing Windows and UNIX I am just trying to get my point across). And what do you mean by it does that directly ? How can a serial port send signals to the CPU ?

I am sorry but I don't understand what you are saying probably because I am starting out with UNIX. Do you think I should post a separate thread about this topic dealing with serial ports and terminal devices ? Because its getting off topic here.

If I am not mistaken you mean that you can move around partitions right ? For example I can unmount the /home partition and put it in a different hard disk all together and use it from there right ?
But then why would you call it "partition nesting" ? because that sounds a partition within another partition.

dpkg-reconfigure

DPKG-RECONFIGURE(8)                                                   Debconf                                                  DPKG-RECONFIGURE(8)

NAME

       dpkg-reconfigure - reconfigure an already installed package

SYNOPSIS

        dpkg-reconfigure [options] packages

DESCRIPTION

       dpkg-reconfigure reconfigures packages after they have already been installed. Pass it the names of a package or packages to reconfigure.
       It will ask configuration questions, much like when the package was first installed.

       If you just want to see the current configuration of a package, see debconf-show(1) instead.

OPTIONS

       -ftype, --frontend=type
           Select the frontend to use. The default frontend can be permanently changed by:

            dpkg-reconfigure debconf

           Note that if you normally have debconf set to use the noninteractive frontend, dpkg-reconfigure will use the dialog frontend instead,
           so you actually get to reconfigure the package.

       -pvalue, --priority=value
           Specify the minimum priority of question that will be displayed.  dpkg-reconfigure normally shows low priority questions no matter what
           your default priority is. See debconf(7) for a list.

       --default-priority
           Use whatever the default priority of question is, instead of forcing the priority to low.

       -u, --unseen-only
           By default, all questions are shown, even if they have already been answered. If this parameter is set though, only questions that have
           not yet been seen will be asked.

       --force
           Force dpkg-reconfigure to reconfigure a package even if the package is in an inconsistent or broken state. Use with caution.

       --no-reload
           Prevent dpkg-reconfigure from reloading templates. Use with caution; this will prevent dpkg-reconfigure from repairing broken templates
           databases.  However, it may be useful in constrained environments where rewriting the templates database is expensive.

       -h, --help
           Display usage help.
