tar file?

... uhm, just as an additional note to your post:

64-@@ grep ^install: setup.ini | grep " 108 " | wc -l
1065
(real tar files (empty), compressed using xz)

If the empty "tar file" is created like this:

64-@@ touch empty.tar (an empty file, but not a tarball!)
64-@@ xz empty.tar

one will get files of size 32 bytes ...

However:

64-@@ tar cJf empty.tar.xz --files-from=/dev/null
      (or: tar cJfT empty.tar.bz2 /dev/null)

one will get files of size 108 bytes (of real tar files).

The latter ones will properly untar, but not the files of size 32.

(yes, in both cases, no files will be produced)

Regards,
Henri
