This looks like fairly typical symptoms of gnutar being broken. What
makes you think that the archive created by BSD tar was invalid?

As a filename should have no bearing on what extended headers
are set.

Why not? In this case, bsdtar is detecting that the file name contains
non-7-bit-ascii characters and is emitting a pax header for that reason;
and since it can't suppress the pax header entirely, it goes ahead and
emits the "not vital but potentially useful" headers for the device #,
inode #, number of links, and high precision timestamps.

I still see no evidence that bsdtar is doing anything wrong.

I suppose this then comes down to the fact that gnu tar is the prevalent
version out there and as such with BSD creating archives which are
incompatible with that leads to problems. From our side we'll have to
switch to using gnutar until this issue is resolved as we need to ensure
compatibility.
