I would just use the built-in guest session feature, and only create a
real account (or even just a root password) for the staff.
https://help.ubuntu.com/stable/ubuntu-help/shell-guest-session.html
"A guest cannot view the home folders of other users, and by default any
saved data or changed settings will be removed/reset at logout. It means
that each session starts with a fresh environment, unaffected by what
previous guests did." (Presumably they can still write to, like, /var/tmp,
but that shouldn't be a problem, and you can set up a thing to clean up
that directory at logout if really needed.)
The normal behavior of auto-mounting flash drives to the current user
works for guest users, too.

Hi,
I am donating two Ubuntu 14.04 machines to a homeless shelter. The shelter
would like to prevent the residents from writing any documents to the hard
drive. The
shelter wants to have residents download stuff to flash drives they are giving
the residents. Googling, I find nothing directly on point. Any help is
welcome.
I did find this
http://forums.linuxvoice.com/viewtopic.php?f=3&t=147
Which talks about locking down the user settings, but it does not prevent
writing to the hard drive.
Thanks!
