# Errors when installing OpenStack Newton on CentOS7 with packstack

While establishing a new OpenStack Newton installation on CentOS7 using packstack, I encountered the following error after running packstack --allinone (doing a multi-node install made no difference, though)

# Openstack neutron could not load ... InterfaceDriver warnings are.. mostly harmless

Unless they're a CRITICAL error, ignore the damn red herrings

# DRBD on RHEL/CentOS 6 fails to sync with UnknownMandatoryTag error

Because error messages just ruin the surprise!

# Why you suffer from "attention residue"

Do you find it hard to switch to a new task, leaving the previous task incomplete? There's a term for that, and it's got to do with how your brain works.
