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.

Thanks for the report, I'll adjust it tonight and carry out a fresh build in rawhide. On a sidenote your change page has an example which does not follow best practice. If you copy over the whole service file from /usr/lib/systemd/system to /etc/systemd/system then any bug fixes or new features added to the service file (security etc) will not be picked up. The proper way is to do a systemd override ... in the case of your example just /etc/systemd/system/sshd@.service.d/tcp_override.conf To override a ExecStart you need to do two lines: ExecStart= ExecStart=@-/usr/sbin/tcpd /usr/sbin/sshd -i $OPTIONS $CRYPTO_POLICY The reason for this is that a single ExecStart will just be executed as if there were multiple lines, but doing the blank one first "resets" the behaviour.
