[LRUG] [devops] enlarge root volume on existing ec2 instance

[Viktor Trón]

Thanks to both of you.

I followed the steps used in Fred's excellent ref
http://alestic.com/2010/02/ec2-resize-running-ebs-root
It is using ec2 command line tools so geekproof.
FYI: you no longer need to run the resize2fs command on your instance, it
is automatically grown for you (at least on my ubuntu 12.04)

If you cringe at the command line but like clicking, the same process can
be done via the aws web console demonstrated in the well-suited medium of a
screencast here: http://alestic.com/2010/02/ec2-resize-running-ebs-root
