disable chrony client log This is only needed to support clients using the interleaved mode. We only use chrony as a server on our network servers and the clients are only using SNTP via xtra-daemon so we don't need this. This frees up a little bit of memory and avoids having a list of recent clients stored in memory. 2024-03-21 03:20:41 +00:00
