System User and Groups
From CBLFS
				This page is created and intended to be a record of all the user and groups that may be created in the wiki. It's main purpose is to prevent overlaps in GID/UID numbers and a quick reference for a damaged/impaired system. If you change a number or add a package that requires a specific User or Group, Please make sure to update this page.
