I want to Ubuntu 12.04 LTS in a work/office environment. The requirements are:
As a Desktop/workstation. I need 1 admin user of type Administrator, with accessed to all apps, and the normal ability to install new apps. Followed by 1 or more standard users. Initially the standards users will/must be confined to one email application (Thunderbird) only. No Web, or anything else.
So the problem with unity is "Dash Home", by simply pressing the "Dash Home" button the standard user can find and run (for example) the web browser, and any other app. I give Ubuntu an A+ for easy access, but that is the problem.
So, I could put the Administrative user into a new group, that is allow to run apps, chown all apps to that group, chmod apps so only this group can execute them, lots of on going work to maintain. Always the possibility of missing an app or two.
If I could just get rid of the "Dash Home" button for all standard users, and remove all default apps from the launcher for each standard user.
