All reports of package-contains-hardlink for the archive. The extended description of this tag is:

The package contains a hardlink in /etc or across different directories. This might not work at all if directories are on different filesystems (which can happen anytime as the system administrator sees fit), certain filesystems such as AFS don't even support cross-directory hardlinks at all.

For configuration files, certain editors might break hardlinks, and so does dpkg in certain cases.

A better solution might be using symlinks here.

Refer to Debian Policy Manual section 10.7.3 (Behavior) for details.
