From this commit: https://github.com/mumble-voip/mumble/commit/6749835aec1419fdea17ff98b9313baeab6e470c
The upcoming release of murmur will handle two new signals: SIGHUP and SIGUSR1.
SIGHUP: Perform a log rotation. This causes murmurd to re-open its log file.
SIGUSR1: Gracefully reload the TLS settings specified in murmur.ini without interrupting service. When this signal is received, Murmur will apply the new TLS settings (certificate, private key, and Diffie-Hellman parameters) to all virtual servers that use the TLS settings from murmur.ini.
Obviously, easy log rotation would be nice.
I use Let's Encrypt, and having an easy way to tell getssl to reload murmur without kicking everyone off would be nice.
