Fixed the permssions on the tarball.
Moreover the remove of the tarball is delayed until the client can work
as a seeder, but after that the tarball is exctracted and removed...
here is the code:
# Extract image.
logmsg "Extracting image from ${bittorrent_tarball} ..."
(cd /a/ && tar -xv${compress}f
${BITTORRENT_STAGING}/${bittorrent_tarball}) || shellout
rm -f ${BITTORRRENT_STAGING}/${bittorrent_tarball}
unset bittorrent_tarball
So you should not find that file in your client when the installation is
finished... and I suppose that if the tarball is correctly exctracted
then it should be also correctly removed... can you check your
autoinstall script?

Fixed in the trunk.
