@jupierce there looks to be some places that still need to be replaced:

Guys, this is way too much output that users don't need. We need to walk some of this back - end users don't (for instance) care about any of the following:

The value of ALLOWED_UIDS is [1-]
The value of DROP_CAPS is [KILL,MKNOD,SETGID,SETUID,SYS_CHROOT]
