are any consequences as for my particular use I doubt any use of
swap occurs. I suspect a workaround might be editing /etc/fstab
all previous installs when a new install is done.

Second Environment:
On a second machine [the laptop being out of service due to
hardware problems] I attempted to install Debian to a USB flash
drive for demonstrating Debian to friends on their machines and
testing used machines before purchasing.

The was no problem until the partitioning phase. It allowed me to
create a ext2 partition on the flash drive for use a / . It
allowed me to create a second partition and to designate it as a
swap partition.

essentially said it was going to *TRASH* the existing install of

swap partition [i.e. changing its UUID].

I see no conceivable reason to mess with a perfectly fine install
when installing to an unrelated device.

Thank you

I often have more than one installation and each new installation includes an
unchanged /srv partition and lists each previous installation as another
available partition unchanged but under an amended name, so instead of / it
may be /wheezyroot. I can then edit the previous /etc/fstab to match the new
uuids and make all bootable. I also find the shared /srv partition useful.

I don't follow your description. Likely I'm missing something "obvious" ;/
I believe you are addressing "First Environment:".
My disk is organized as:
/dev/sda1     A fairly stable (for me) Debian install
/dev/sda2 swap - partition choice a historical accident but no reason to change
Remaining Debian installs are in logical partitions >= /dev/sda5 .

I follow the defaults as to putting / et al in a single physical partition.

Thank you for responding.
