As announced earlier this year, we plan to deprecate TCP wrappers out of Fedora services in a single release (Fedora 28) to avoid user confusion that some of the tools will be using it and some not. For more information about the change or possible migration paths outside of the package itself, see the linked accepted Fedora 28 change. This report is for a source package, that has "BuildRequires tcp_wrappers" in spec file and resulting packages depend on "libwrap.so.0". The changes to remove the dependency should be minimal, usually a configure switch, but let me know if you will need some assistance with the changes. Additional info: https://fedoraproject.org/wiki/Changes/Deprecate_TCP_wrappers
The gsi-openssh package closely follows the openssh package in what patches it applies and what configure options it uses. When openssh stops using the tcp-wrappers then gsi-openssh will do too, since changes done to the openssh package are ported to gsi-openssh package. If there was a similar bug for openssh for this change I would mark this bug as dependent on that one, but I can't find one.
