I have to admit that over the past 3 decades of working with Unix-y systems, there's been a number of times I've had to resort to 'od -cx /your/dir/here' to debug issues (/bin/ls -fi is *almost* equivalent, but doesn't show holes in the directory) The biggest danger I can see is some shell script doing something like: foobar > $dir/$targetfile and $targetfile is unset. If we allow a program to get an open fd that refers to a directory, what are the semantics of various operations on that fd?
