I was wondering, how much truth is there to these claims (the one about bloat)? Furthermore, are the costs 'justified'? (Obviously there are unavoidable cases su...

I do not want to add another dependency to my application by requiring the user to install libuuid (seems like libuuid isn't included in most Linux distros, like CentOS).
