Hi,

The kfreebsd-10 (kernel) packaging distributes a source tarball in                                                                                                                                   
kfreebsd-source, a binary arch-indep package.

Files and directories in the tarball are owned by root:src, but
permissions depend on the package builder's umask setting.  To ensure
reproducibility, I guess we could chmod before building the tarball:

--- debian/rules	(revision 5716)
