Just to make sure I understand you correctly: You do not intent to
maintain VistA installations for different clinics on the very same box,
right? You are just proposing that different clinics might have a need
to use different installation pathes on their very onw box.

This is true for code which is not changed. You should try to keep the
academical case in mind that /usr might be mounted readonly (for
instance for secutirty reasons).
Data which are subject to change (the actual database) needs to go to
/var most probably to /var/lib/VistA in our case. If you want to
maintain different versions you should use
/var/lib/VistA/<version>
As I suggested in a mail some weeks ago: Having a look at the
postgresql packages in Debian and how they organise their stuff to
enable simple upgrades might be quite reasonable to copy the principles
of installation.

Debian packages do NOT use one of these directories. This is not
compliant to Debian policy. For sure local admins can do whatever
they need, but the packages should not touch these directories.
Kind regards
