Golden Disk Image Assistance

Hello,

I'm looking to create a golden disk image according to this article: https://library.linode.com/server-builds

Of the "storage options" listed I'd like to use is "Different Computer".

I tried copying the image over SSH (https://library.linode.com/migration/ssh-copy), which works. What I didn't realize is that it copies the entire image, not just files, which ended up being 50GB. Which isn't optimal for uploading to another Linode obviously.

So I think I know my next steps in order to make the image smaller. Can you confirm I'm thinking right?

1. Resize the main disk image (/dev/xvda) from 48640MB to the roughly the space used - currently it reports with "df -h" that I've used 1.9GB. So I'm thinking resize it to 2.5GB.

2. Download the image.

3. Resize the main image back to 48640MB

Now the steps for a new Linode to use that image would be:

1. Create Linode with the main image being the same size as my source image (2.5GB)

2. Write my saved disk image to the new Linode at (/dev/xvda) over SSH in rescue mode

3. Resize /dev/xvda to the desired size, probaly 48640MB

One other thing I'm unsure about is configuration profiles. The image I'd like to save and use for future instances is based on Linode's current CentOS 6.2 profile. If in the future I setup a new Linode that's based on a CentOS 6.4 configuration, how will that effect the image I have saved to re-use?

Thanks!
