what´s exactly the problem with crashtest?
His incompetence is a real problem paired with his feeling he should educate other users (by writing 'guides' being a compilation of his beliefs, establishing bad practices and polluting this forum and Github issues with nonsense). As often incompetent people don't realize how incompetent they are but it's important that they know since how could they improve otherwise?
The amount of insane BS originating from this single user was that immense that I dedicated some time trying to explain stuff to him over the last 2 years. Worked somehow in the beginning (a lot of complaining in the first place, then months later he adopted some knowledge) but this changed over time. He now outright refuses to learn while continuing to pollute this forum.
When a newbie reads through the forum he can come across complete and utter BS like short SMART selftests would test for surface errors, all this FUD about btrfs, a collection of weird stuff that would be needed to 'Connect to OMV SMB shares with Windows 10 and Microsoft Servers' from someone who doesn't even understand what a domain is and what's necessary for a host to join a domain. His 'guide' and 'advices' introduce more problems than they solve, for example there exists neither an excuse nor a reason to recommend 'guest logons' any more, and so on. He barely understands the meaning of the words he's throwing around and lacks especially any networking knowledge (while feeling he would know more than people who do this for a living since he's using Windows on his desktop machine).
Next annoying detail is methodology: OMV is based on Linux, for every problem someone runs into it's really easy to diagnose what's going on by optionally increasing the log level and looking into or providing the logs. This is important for us developers to nail problems down and it definitely doesn't help when people like him encourage users in threads to rebuild their whole system for no reason and to follow completely stupid trial&error tasks in 'wild guesses' mode instead of following an analytic approach working through potential problems from bottom to top.
How does this affect the development work? Well, it sucks. His lack of knowledge and methodology results in BS like this and that. Since he refuses to learn anything and as such also the difference between kernel and userland he doesn't understand the principles and challenges creating something like this but feels encouraged to spread concerns about the use of the RPi image. As such new users now think they would deal with new bugs while in reality nothing has changed with the RPi 4 image other than added hardware support as outlined several times. If users like @ManuelM now struggle with the image on their RPi 4 they struggle for exactly the same reason other RPi users did in the past: the necessary additional bits weren't installed on first boot.
To make things worse @crashtest in the meantime tries hard to agitate users and his mission is get me out of this forum (of course he's not able to distinguish between contributions to a project and writing forum posts). I feel ashamed reading all the FUD and BS that is spread here since so much is the absolute opposite of how things work in reality. But the worst part of the @crashtest problem is not his own incompetence but that he feels encouraged to continue with his idiotic behavior: refusing to learn, spreading BS, sabotaging development work.
I don't want to contribute any more to such a project that's tolerating or even encouraging such behavior, as such no more fixes for the various ARM images (RPi included) and no more knowledge contributions. No more feedback on 'TimeMachine with SMB' and the preparations for OMV5 images for ARM were sent to the bin (easing a lot of stuff e.g. using the same hostname 'omv5.local' on all images allowing people to overcome the stupid 'static IP address' madness).
Speaking about improvements. It doesn't help to improve software if then incompetent people who are stuck in last Century advocate anachronistic mechanisms via 'guides' and flooding the forum and try to convince users that stuff that works flawlessly would be a bad idea.
I lost too much time already and it simply makes no sense to continue 'against' retired guys armed with huge amounts of spare time ready to invest into idiotic games instead of improving their skills. @crashtest's latest mission is to get me out of here and eventually he succeeded. Now everybody can be happy again since nobody will comment any more on the flood of FUD and BS.
