Dear axls,
It seems that you are realy concerned about what you think that is going on on your system and sincerely try to get help here. Now try to read the whole thread again and take it easy. What do you think the impression people here got from your first post to begin with. You are talking about compile options for generating the software in the packages for openSUSE in general. Not something that I, and I guess many others here, are expecting from somebody stating “I’m a desktop user” later. Also for many of us you seem to jump to a conclusion without realy researching in depth what the several “strange things” you found mean. Part of that searching could be: Asking here. The simple question: " I found the zero length file success in my root directory after install, is that normal?" would have given you a solution in a nick of time. But people here see with amazing that you, without having any doubt, interprete this as one of the results of your system being cracked. Some people migh come to the conclusion you are lightly paranoic. And your other “strange things” are probably (some for certain) in the same catogory: that jus just normal or you must have inflicted this yourself.
Some people here even are afraid that your unsupported claim that openSUSE in particular and Linux in general is very vulnarable to crackers by default, might bad for Linux’s reputation.
Nevertheless, I read that several people above try to help you in a way to let you identify one by one the “strange things” in such a way that they can be analysed. Thus we and you can come to a conlusion which ones are normal, harmless or dangerous. That is how IT problems are to be handled: systematic, trying to understand and not revert to that old human habit: jumping to conclusions.
That means that for every one of the statements you make, they will ask for evidence. E.g. when you say your home directory is moved, then tell us more about how you came to that conclusion and preferably show this with things like
ls -l /home
and the same for the place where it moved to. And when you say you do not know where it moved, how can you then state that it is moved. I would in that case state that is is removed/deleted. Mind your words. People here are like computers, they do not understand what you mean to say, they understand what you say.
Please, do not take our words as if you are not welcome here. You are. But keep in mind that all the people here are openSUSE users like you. They try to help in their spare time. Their only reward being that sometimes people are helped and post something like: “Thank you for your help, it worked!”.
Keep in mind that people do not know you nor your knowledge base or experience. They have to assess it from what you say, starting with your first post. They can guess wrong. That can be because of wording used in posts, because of English not being the first language of one or more of the posters, because of complete misunderstandings. We are all away from each other over the globe in time and space and nothing is in fact “logical” in such a conversation.
I guess that if you are willing to post now one by one your concerns with your system, many good advices will be brought forward.
Wishing you success with openSUSE
