- With those "other" systems, you must mean BSD like systems.
- The problem with BSD like systems are, that they do not use the "type" field
- in the tar headers. A directory is type "5", but this is ignored by BSD.
- They look for only the '/' suffix. The tar command on SVR4 has had a LOT
- of changes put into it to make it read all kind of weird archives from Xenix,
- BSD, multi-floppy archives. All issues resolved by teaching SVR4 to
- understand
- the whole world. This last issue I think should be resolved by BSD tar.
- A BSD tar archive has filetype '0' (impossible) for all files/directories.
-
- tar compatibilies:
-
- AIX -> BSD OK, Since a AIX tar has only files, no
- directories. (No problem of no '/' suffix)
-
- BSD -> AIX OK, AIX understands that '/' suffix really
- means filetype '5'.
-
- SVR4 -> BSD Problem, since SVR4 archives has directories
- and are not using the silly '/' suffix.
- Instead we are using the tar filetype field.
-
- BSD -> SVR4 OK, since SVR4 tar has been fixed to take
- special care of BSD archives. Like above
- for AIX.
