All reports of debian-rules-is-symlink for the archive. The extended description of this tag is:
The file debian/rules is a symlink instead of a regular file. This is unnecessary and makes package checking and manipulation more difficult. If the rules file should be available in the source package under multiple names, make debian/rules the real file and the other names symlinks to it.
This problem may have prevented Lintian from performing other checks, leading to undetected changelog errors.
This tag has not been emitted in any package tested by Lintian.
