I would recommend being quite draconian and pretty much disable the whole
Maintenance menu and quite a bit of the services menu as well. And then
train them really well on the remaining parts, and creating a targeted,
short and simple manual (ideally accompanied by some video clips) so that
support can be kept to a minimum (or at worst done over the phone).

The emphasis on eliminating moving parts and sources of error of course also
harks back to you "DHIS appliance" idea, Bob. One could even think of
running DHIS Live with H2 off USB sticks (though they are flimsy), which
could even be made to boot up something like DamnedSmallLinux.
