Why?  do you have a slash at the end of $LFS?  Not that it makes any difference.

ls //// is the same as ls /

That's what the POXIX standard says.  Try it.

Just tradition.  The dump column is for a command named 'dump'.  We don't have 
that as it's quite obsolete.  You can set the value in the dump column to 
anything you want, but you need something there.  My view is that the dump 
column just gives an indication of a physical disk -- so I use 1 for real 
partitions that can be written (not dvd. etc) and 0 fro everything lese.
