busybox tar fails to unpack gnutar tarballs

[proche@rainmaker.com]

systemimager-bittorrent-4.1.99.svn4556_bli-1
gnutar 1.17
sali 1.5.2

while attempting to reimage with PROTOCOL=bittorrent, busybox tar is having problems unpacking the gnutar tarball

tarballs are created with:
tar -czSpf

unpacking with:
tar zxvf

result:
tar will begin to unpack some files then skip over large parts with the error msg

tar: warning: skipping header 'S'
tar: invalid tar magic

We are using the tar and gz tools that come with Busybox. To resolve this issue you must omit the flag -S. To do this you must edit si_installbtimage and on line 323 remove the S.

So before:

system "cd $dir/$name && tar -c${compress}Spf $tarball_file .";

After

system "cd $dir/$name && tar -c${compress}pf $tarball_file .";
