install_chrome.sh script is out of date

[rklrkl]

https://github.com/khilnani/devops/blob/master/centos/install_chrome.sh is quite out of date (over a year old). Please update it with the latest release from http://chrome.richardlloyd.org.uk/install_chrome.sh

It may be preferable to replace it with a 3-liner script that does what the script's Web site instructions suggest:

wget http://chrome.richardlloyd.org.uk/install_chrome.sh chmod u+x install_chrome.sh ./install_chrome.sh
