The V7 dump and its descendants (S3 dump, 4.1BSD dump, 4.2BSD dump) *do* know
the difference between directory inodes and non-directory inodes; they first
dump the directory inodes and then dump the non-directory inodes.  As such,
"restor" can - and does - build a model of the portion of the directory
hierarchy which was dumped onto that tape (if any file was dumped, it dumps
all the directories leading up to that file whether they changed since the
dump date or not), which is how it can find files by name.
