All reports of conffile-is-not-in-package for the archive. The extended description of this tag is:
The conffiles control file lists this path, but the path does not appear to exist in the package. Lintian may also emit this tag when the file exists, but the canonical name is used in the "conffiles" control file (e.g. if a parent segment are symlinks).
Note that dpkg and Lintian strips all whitespace from the right hand side of each line. Thus it is not possible for a file ending with trailing whitespace to be marked as a conffile.
Severity: important, Certainty: certain
Check: conffiles, Type: binary
This tag has not been emitted in any package tested by Lintian.
