This document, Chapter 5 of the ETOS manual, describes the ETOS user account structure and file management. Key topics include:
- Account Structure: How system managers assign disk sections as ETOS accounts and the importance of preventing multiple users from logging into the same account to avoid directory and file corruption.
- Account Attributes: Details on account numbers (project and programmer numbers), passwords, protection codes (which determine privileged status and memory allocation), and creation dates.
- ETOS File Attributes: An explanation of User File Directories (UFD), file naming conventions, and reserved file names for OS/8 and COS storage.
