   One un-sexy and yet critical aspect of filesystem design is all the   
   edge cases you can encounter during panics at each possible combination   
   of states.  DEC famously engineered the sequence of I/O's in moving   
   filesystem state to disk so that they could make firm statements   
   about the worst case.  Log-based filesystems get there with their   
   parallel data structure with its own commit semantics.   
      
   If you punt, then count on your fsck-ish program becoming quite   
   complex, with some bad cases where corrupt data has to be abandoned,   
   or batches of content without name end up in a lost+found directory.
