Although not on CentOS, I've been forced to use it with serial-getty@.service (even after enabling and starting it) to get the OS to display a console prompt after an OS upgrade. In this case I used Restart=on-success and RestartSec=5 (the latter an arbitrary value) because agetty exited after the first console disconnect.

I've been trying out the Restart= option in some of my own systemd service unit files - which appears to work fine
However, I notice that this option is only used in a few OS provided service unit files - and was wondering about the wisdom of adding this capability to other daemons/services? (e.g. chronyd or ntpd, crond, rpcbind, etc, etc) - not that these daemons are likely to crash and need restarting that often ...
Previously, I've used custom scripts to monitor the state of key daemons and restart or report their status as appropriate - but as systemd has 'Restart' and 'OnFailure' capabilities build in, these options could potentially make (my) life a bit easier ...
Are there any potential pit-falls in using Restart with OS provided daemons/services?
Thanks
