Indeed, upgrading an existing installation is always risky and should have a
dry-run on a backup system first of all. If that works, then you can take the
learning and upgrade your production server (just for the records: In complex

Server *should* run under their dedicated users!

Indeed. No point in having a separate gnuhealth-user.

Will you then have different packages for tryton and gnuhealth?
IMHO, tryton is the foundation, and gnuhealth should use what tryton provides.
So fiddeling around with another user is not best practice. It may be
appropriate in small desktop installations, but at least for a production
environment I personally would step away from it.
But as always in OpenSource: There's more than one way to do it.
