The original V7 tar was not quite graceful about directories and that image was probably not written by an original V7 system. The directory issues were fixed quickly. You need a new tar, such as the one from 2BSD to read that tape without error messages, although I suspect the original will read it if you do something like:
tar vtf foo.tar > tapedirectory grep and filter the directories tapedirectory and make a directory.list then read that in a script that does mkdirs on the files in directory.list Also warming, mkdir -p probably does not exist in V6 or V7 IIRC Finally, 1BSD (aka BSD) was based V6, 2BSD was for V7. It was originally a tp tape, if you have a tar image of it, it was converted by someone.
