Yes, you had indicated that it should work, but then, others, like
shown in the post above, apparently indicated that to install and run
Debian 6 LTS on a computer that already had Debian 7 installed,
required the use of virtiual machines, and I have no experience in the
installation, administration, and use, combination, regarding virtual
machines.

Many years ago (about 20-25, I think), I used something with a name
like CP/CMS, or, CM/CMS (from memory), that was, I think, a multi-user
virtual machine, running on a mainframe computer that simultaneously
ran (although I did not use it) multi-user CICS/COBOL, but I have no
experience other than what I had then, as a user, relating to virtual
machines, so the suggested, apparently required, installation and
administration and use of virtual machines, in order to install and
use Debian 6LTS, on a computer that had Debian 7 already installed,
appeared too complicated for me.
