- I disagree. There are just too many organisations using ANSI format magtapes.
- Tar and CPIO should both be retained, but the ability to read and write
- standard ANSI magtapes... if the hardware is available... should be part
- of a portable operating system standard.
ANSI tape can be supported via a set of programs over the
standard Unix system (ConvexOS 8.0 and above do so, along with many
other "mainframe" tape subsystem features) but ANSI labeled tapes are
inappropriate for file archival. With a properly designed ANSI tape
subsystem, it is easy enough to have tar, and cpio (and even
dump/restore) use ANSI labeled tapes, and it can be totally transparent
to the user.
Thus, we have the POSIX standard archive on the ANSI standard
magnetic tape format..
