I'd love to use something like ZFS to handle this storage, at which point this wouldn't be an issue, but I have to work under the constraint that various teachers acting as Windows admins need to be able to manage the servers. More money would solve this problem for me.
Money aside, it's galling that the developers aren't building for the enterprise deployment case. I WANT to run Chrome _badly_ in corporate environments but it's not engineered for my use-case.
You can find it by going to "Install Chrome for all user accounts" http://support.google.com/chrome/bin/answer.py?hl=en&ans..., which points to "Alternate (offline) Google Chrome installer (Windows)" http://support.google.com/chrome/bin/answer.py?hl=en&ans...
You want the "Alternate installer for all user accounts" (https://www.google.com/intl/en/chrome/browser/eula.html?syst...). That will install Chrome in the Program Files directory.
We're using the "Enterprise" MSI-based installer. We are seeing difficulties with it. It's storing large DLL files in each user's user data folder, which we're putting on a server so that user settings will "follow" them from computer-to-computer.
