ufs and ext

[.VWV.]

Hi to all.

I have noticed both BSD and Linux pre-compiled kernels cannot mount read-write 
the other filesystem. It's a shame that a newbie could think one is able to 
read, the other one is able to write. We know ufs was born before ext. Some 
Linux distributions has also adopted ReiserFS on Linux, that's really a 
not-unix filesystem. Why at PASC nobody has declared what's the best 
standard?
I'm waiting for God's reply...

With my best regards
