We uses AmbientCapabilities directive on systemd unit, but it does not work on older kernel, causes following error: "systemd[5370]: Failed at step CAPABILITIES spawning /usr/bin/scylla: Invalid argument" It only works on kernel-3.10.0-514 == CentOS7.3 or later, block installing rpm to prevent the error.
