Daniel, what are you trying to achieve here?

I thought you wanted to create interest for your filesystem and acceptance 
for merging it.

What I see you are actually creating tough is something different.

Is what you see after you send your mails really what you want to see? If 
not… why not? And if you seek change, where can you create change?

I really like to see Tux3 inside the kernel for easier testing, yet I also 
see that the way you, in your oppinion, "defend" it, does not seem to move 
that goal any closer, quite the opposite. It triggers polarity and 

I believe it to be more productive to work together with the people who will 
decide about what goes into the kernel and the people whose oppinions are 
respected by them, instead of against them.

"Assume good faith" can help here. No amount of accusing people of bad 
intention will change them. The only thing you have the power to change is 
your approach. You absolutely and ultimately do not have the power to change 
other people. You can´t force Tux3 in by sheer willpower or attacking 

On any account for anyone discussing here: I believe that any personal 
attacks, counter-attacks or "you are wrong" kind of speech will not help to 
move this discussion out of the circling it seems to be in at the moment.
