It seems that base-files has an 'x' extended header for each file, apparently to

That's a result of me having built that file on openSUSE and openSUSE's
decision to default to POSIX format instead of GNU.

Hmm... maybe I should drop this patch, if the correct thing to do is to
build base-files with tar --format=gnu?

If your patch allows to unpack a POSIX tar archive correctly, without
generating a warning... why would you like to drop it?

POSIX tar archive are (potentially) not unpacked strictly correctly in both cases, as they contain extra information that setup does not interpret.

All this patch changes is if we warn about that loss of information, or silently drop it.
