Maybe you wrote a filesystem 30 years ago when everything was BSD FFS, but
things have moved on from that time.  I'm one of the maintainers for ext4,
principal architect for Lustre, which is arguably the largest and fastest
filesystem ever made, and sometimes contributor for ZFS, so maybe you need
to rethink your comment about my filesystem expertise. :-)

My "personal" attack was only an observation after being on this list for
10+ years that your sole contribution here is mostly "Schilly tar does this
differently".  It isn't clear why you are on this list except to promote
your own product, since it doesn't seem you have an interest in contributing
to improving GNU tar.

My interest is to ensure that GNU tar works properly with modern filesystems
that don't necessarily conform to unstated assumptions in POSIX that you have
from 30 years ago.

Cheers, Andreas
