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.

In UNIX, you could attach the new drive's partitions wherever you wanted -- /home/ for example, if that particular folder is very big.

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.

REPARTITION(8)						      System Manager's Manual						    REPARTITION(8)

NAME

       repartition - load a partition table

SYNOPSIS

       repartition device [partition-file]

DESCRIPTION

       Repartition  uploads  a new partition table for the partitions of device.  The table is obtained from the first sector of partition-file if
       given, device otherwise.  Device may refer to the whole drive or a primary partition, depending on whether you want to upload  a  partition
       or a subpartition table.  The partitions will be truncated to fit within the enclosing device like the disk driver does, unless the numbers
       are coming from partition-file.

EXAMPLES

       repartition /dev/hd0
       repartition /dev/hd4 /etc/hd4.table

       Reload the partition table of drive 0 setting /dev/hd[1-4], and the subpartition table of /dev/hd4 setting /dev/hd4[a-d] using a file.  The
       latter may be useful if you need more than the 4 subpartitions a single Minix partition gives you.

DIAGNOSTICS

       The new table is printed on standard output.

FILES

       /dev/hd[0-9]

SEE ALSO

       hd(4), part(8).

BUGS

       The disk must be in use for the changes to stick.  The partition table of an idle disk will be reloaded on the first open.
