My comment was meant to say there is no reason development HAS to stop. People's will to
continue development is a different matter entirely.
Reiser4 attempts to solve different problems than other filesystems being actively developed.
There is no doubt that Hans' relationship with the kernel development community caused a
serious disconnect, but at the same time, most filesystem development is aimed at solving very
real problems we experience today. Snapshots, better performance, higher capacities, etc.
