"removed"?  Nothing at all was ever removed from the new 'tar'
implementation as far as I can tell!

Perhaps you might ask Keith Muller why some kind of file-by-file verify
option was never added in the first place -- I sure as heck can't tell

(FYI, 'tar' has _never_ been "hijacked" by GNU -- but NetBSD seems to
have been hijacked by GNU, or at least the GNU 'tar')

I sure as hell don't know where you got that idea from.

Of course personally I wouldn't ever use anything like 'tar' or 'cpio'
or 'pax', etc. to back up filesystems unless they really know a heck of
a lot about what they're doing and what risks they may face by doing so.

On NetBSD Amanda does just fine with proper 'dump' backups which of
course face none of these silly issues because 'dump' is a proper backup

Don't you know yet that PAX and the various TAR and CPIO formats are
archive interchange formats, not backup formats?

I don't know what you're talking about here either.  NetBSD 'pax' (and
its 'tar' and 'cpio' front ends) does not give up if a file changes --
it just reports an error (from buf_subs.c):

        else if (arcn->sb.st_mtime != sb.st_mtime)
                tty_warn(1, "File %s was modified during copy to archive",

apparently just like your commercial software package also does.

Isn't it nice when NetBSD's free tools have some of the same high
quality features as expensive commercial software?
