We have a toolkit that includes such things as:
showing which cylinder groups a file was allocated into
or
dumping all the blocks a file is on...
I've often wanted this. I wonder if it is worth importing it
or making it a port?
They are in C++ (but not written by a C++ expert)
and don't know about UFS2 yet..
e.g. (excuse linewrap in output)
