All reports of debian-control-file-is-a-symlink for the archive. The extended description of this tag is:
The debian/control file is a symlink rather than a regular file. Using symlinks for required source package files is unnecessary and makes package checking and manipulation more difficult. If the control file should be available in the source package under multiple names, make debian/control the real file and the other names symlinks to it.
Severity: normal, Certainty: certain
Check: control-file, Type: source
