Error when installing Zenoss in Centos 6 Docker image

This happens when using auto-deploy installation (hint).
# ./
The error happens in when the zenoss service is started.

Zenoss not initialized. Performing first-boot initialization... Fresh install pre steps Checking RRDtool version >= 1.4.7: [FAIL] Missing. Error: rrdtool is not in the search path. Please confirm that RRDtool (version >= 1.4.7) is installed.
It can be verified that rrdtool is already installed.

The routine that checks for rrdtool is in /opt/zenoss/bin/ Look for confirm_rrd(). It uses the command `which` that is not installed by default in the Centos 6 docker image.

Reset or fixing display settings in Mac OS X 10.10 (Yosemite) for external display LG 22LS2100

For some reason after the Yosemite installation when I tried to change the Display Settings to "Best for Display" resolution font smoothing just went crazy. I tried to do the following without any effect.

Forcing RGB mode - I did the workaround suggested by the author (taken from a commenter)Changing Font Smoothing Settings in Yosemite The workaround involves creating a new user and re-logging in to that new user. I know this is painful but for me this is a quick workaround because the old user is disposable for me. In the new user I notice that the Display Settings resolution is scaled but it does not indicate which scale it used. The BIG NOTE is not to use auto-scale resolution this time in the new user.
