With Kees' patches now merged into my modules-wip branch (warning, rebases frequently), this should be pretty simple. Dmitry? The question of whether this falls back to appended signatures if there's no xattr support, or whether we fix cpio depends on whether someone is prepared to do the latter. As Mimi points out, AIX, bsd, solaris all have versions of cpio that support extended attributes, as does the bsdcpio Debian package, for example.
