The group's and others' permissions in the tar archive don't matter. They have no meaning on the local system.

It doesn't serve any particular purpose. Correction: The group's and others' permissions, regardless how they are set in the tar archive, don't serve any particular purpose. You should consequently demand that an archive format is used which does not transfer group's and others' permissions at all. > (c) Some users may get screwed over by virtue of the fact that those > files are listed in the tar archive with world-writeable permissions. Correction: Some users who set a wrong umask when creating files by extraction from these archives and then attempt to build an own kernel from that may screw themselves over. The danger here as that users who handle umask in a wrong way actually run self-made kernels. _This_ is what you should campaign against first. -- Stefan Richter -=====-=-==- =--= -==-= http://arcgraph.de/sr/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
