Some people actually prefer filesystems over raw devices for a variety of reasons: - each file brings its own address space, which offers memory protectio= n from other processes, - files can have owners and permission bits, - files hide the fragmentation of the underlying device from users, - a file system provides a common and well-understood api for devices with less common or well-understood apis, - etc. Those reasons are as valid for azfs as for any other filesystem. I hav= e no doubt that azfs is useful. It probably wouldn't hurt to express the merits of the filesystem and the problems it is supposed to solve a little better. So far most criticism was based on the fact that noone understood what the hell it was all about. My personal question when looking at this is: Why not use ext2? It appears to me that an ext2 mounted with '-o xip' would solve the same problems.
