Are there licensing issues in modifying an existing public AMI and making the modified version public?

Assuming you don't have any GPL code actually in your software, including it in the AMI would only require you to release your software under GPL if it was part of the terms specific to the AMI. The part I am unsure about is if you would be required to supply the source code to all of the GPL software in the AMI, hopefully someone else can clarify this for you. The safest option would be to just release a package for the distribution and possibly a shell script to automatically install it and any necessary repositories.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
