| 5 | ## The template containing rules common to unprivileged | |
| 6 | ## users and administrative users. | |
| 7 | ## </summary> | |
| 8 | ## <desc> | |
| 9 | ## <p> | |
| 10 | ## This template creates a user domain, types, and | |
| 11 | ## rules for the user's tty, pty, home directories, | |
| 12 | ## tmp, and tmpfs files. | |
| 13 | ## </p> | |
| 14 | ## <p> | |
| 15 | ## This generally should not be used, rather the | |
| 16 | ## unpriv_user_template or admin_user_template should | |
| 17 | ## be used. | |
| 18 | ## </p> | |
| 19 | ## </desc> | |
| 20 | ## <param name="userdomain_prefix"> | |
| 21 | ## The prefix of the user domain (e.g., user | |
| 22 | ## is the prefix for user_t). | |
