Re: [ros-dev] Security policy for FAT partition driver?

[Phillip Susi]

How exactly are xattrs stored on disk?  Is it possible and efficient to 
store a dozen xattrs on a file of various sizes from 1kb to several MB? 
  How would you reconcile the two different sets of owner and access 
information associated with the file?  For instance, if someone creates 
a file on the partition from Linux, then you mount it with ROS, who owns 
the file?  Who has access to it?  Linux would only place some 
meaningless uid and chmod mask in the inode, so how would ROS come up 
with a sensible security descriptor for the file when one does not 
already exist?

These are the kinds of problems that make attempts for ReactOS to share 
a unix filesystem ( and vice versa ) kludgey at best.
