| 8 | # 0 = success; causes "OK" to show up in checklist. |
| 9 | # 1 = failure; causes "FAIL" to show up in checklist. |
| 10 | # 2 = skip; causes "N/A" to show up in the checklist. |
| 11 | # Use this value if execution of this script is overridden |
| 12 | # by the use of a control variable, or if this script is not |
| 13 | # appropriate to execute for some other reason. |
| 14 | # 3 = reboot; causes the system to be rebooted after execution. |

| 17 | # stdin is redirected from /dev/null |
| 18 | # |
| 19 | # stdout and stderr are redirected to the /etc/rc.log file |
| 20 | # during checklist mode, or to the console in raw mode. |
