syslog-ng will replace rsyslog as default logging in the future ?

I don't know, haven't taken a poll or anything.  So far it's just a test on the netinstall.  Have you had any issues with it?

The reason for the change: https://www.rsyslog.com/clarifying-ai-f … r-rsyslog/
Of course, you're free to remove syslog-ng and replace it with rsyslog after the installation is complete.  And I may change the default back later, if that's what most users want.
