That's why I trust git more than anything else, especially compare to the typical "Anti-virus" software. git is written by Linus, open source, whole algorithm is based on file content change detection, base on hashes, etc. If my server software is corrupted initially by XXX gov agency at the Debian website, well, I can't do anything about it. If someone did management to add any additional software to the server after I add all file contents to git and clone it to a different server, I have strong confident I can detect any changes happen in the system with ease. Patio11, I have great respect for you works, blogs, etc. Assume you can hack/overwrite any piece of code in that server to anyway you want, what kind of changes can make so my git clone/backup system failed to detect your changes? Even if you can hack the git executable to tell me nothing has changes, I think when I do a remote git pull with the original git binaries, I can see the modifications. Right?
