3 ) FAQ’s

1Q ) Is this starting and restarting a traditional “start/stop” or a faster  “standby/resume”?

A ) It is start/stop, standby/resume would require saving memory and OS state and that is not supported.

2Q ) By default the size of root partition ( /dev/sda1 ) is 15GB . How do we increase this value when you launch it ?

A ) Resizing the root partition on launch can be done as follows:

[bash]ec2run  ami-b232d0db  -b  /dev/sda1=:100[/bash]

Should you wish the volume to not be deleted when the instance is    terminated, the following command can be used:

[bash]ec2run ami-b232d0db -b /dev/sda1=:100:false[/bash]

Note the addition of ‘ :false ‘ to the previous example.
