The EPA has a very limited use of *nix OSes. Individual sites seem to dictate their own policies in the application of *nix. At my location it has been outlawed in the desktop, but is used as a dhcp server and probably some other limited functions. Personal I wish that we used it more, because I feel it's more stable, cost effective and the OS is more interest, but there's clearly an adversarial position that has been taken in the use of *nix OSes. The agency standard mail is Lotus Notes and I would love to install Domino on Linux to work with as an admin, but our site fears that we would be unable to completely secure linux. I pray that other agencies have better luck using alternative OS. I don't always feel that linux is the best (example #1 I would not install it on the desktop without a Lotus Notes client, because our end users are confused enough with Windows), however I think many task would be performed better and easy on a *nix OS (example #2 a new workstation was purchased to implement a web based kiosk, when the same old system could have be reformed with linux and run just as well. I'm thinking the Gov paid atleast $800 for the workstation + $120 for Windows 2000). For an agency that is on a budget I think EPA spends money like their funding is limitless.
