Anyone upgrade their installation from CentOS7.3 to 7.4?  I needed that 
upgrade on other systems due to some patches that wouldn't be released 
to 7.3.  I've had no issues with 7.4, so I'm wondering if anyone has run 
into Observium related problems with 7.4?  It only came out officially 
in the last few days, so it may be too early to ask.
