This may come as a bit skeptical, but IMHO the large scale adaptation of a Linux distro in Indian state departments seems a long way to. The lack of Linux operational training to the personnel along with replacement costs may call for an early demise to the plan to switch to Linux. While it does sound promising, the average government clerk in India, is computer literate in terms of Microsoft Office suite. Replacement of MS Office with Libre/Open Office suite itself is a big hurdle which in terms of usability is still in its early days. In addition, most systems on government offices I've seen run IE8 as their primary browsers, running applications "designed for IE only". I believe that if the switch to a Linux distro is to be made, the government should start with replacing leagcy windows software with their open source, linux compatible counterparts, before making the big move.
