comment how do you add an A record for a root domain
I generally don't like CNAMEs either, but instead use a pre-processor to fill in IP addresses, and assign both IPv4 and IPv6 addresses. It's faster too.

comment Authentication / Encryption methods for distributed nodes?
Kerberos uses key files, stored locally, that are the equivalent of x.509 client certificates. They can be stored encrypted, or as often is the case, unencrypted for use by services. If you choose to store them encrypted, each device will have to get a decryption password on service startup, which sounds like something you don't want t do.

comment Why is DU causing high CPU usage?
You ran that from /home ? If so, then you don't have any hidden directories inside /home itself...

comment Why is DU causing high CPU usage?
Is it possible one of those is the culprit? Try: du -sh .??* from home and see what happens.

comment Virtual Machines - Possible to Restore Replace Kernel without Rebuild?
Many admin use the "nuke it from orbit, it's the only way to be sure" approach to security breaches anyway. Also, this lets you keep the old VM around for forensics as it remains mostly untouched, other than to disable remote logins perhaps while you move the data over.

comment Setting up FTP (vsftpd) on Ubuntu 12.04
You are able to connect but not log in from the machine itself, or from another? Also, is there any logging going on in any of the syslog files indicating an authentication error, or some other error?
