The Indian newspaper The Hindu reported last month that the Information Technology department had issued an order which said, in part: "Consider installing BOSS [Bharat Operating System Solutions] Linux as one of the mandatory operating system."

India decided three years ago to launch a new ICT policy based on the mandatory use of open source operating systems. In November 2011, Tamil Nadu introduced BOSS GNU/Linux, a derivative of Debian GNU/Linux, to be installed and used on government computer systems.

BOSS GNU/Linux has support for all major Indian languages, bio-sensing devices and digital signatures.

As The Hindu pointed out, apart from the cost savings, it was the reduced risk of being infected by viruses or affected by hacking or phishing attacks that led India to introduce the new operating system.

"The huge investment cost involved in purchasing closed source software [such as Windows XP] may be avoided, which in turn translates into huge savings for the government," the Tamil Nadu government order said.
