 |

Hi,
I am perfectly content to use the sudo solution to allow regular users to reboot and halt the system, but I was not able to find how gentoo limits /sbin/halt to superuser only. I'm just curious for my own education. Any good links to this info?
thanks |

| I presume its just checks for the running user being UID 0. A check of the source would confirm that though. |

Yep, I just looked:
from the halt.c code
| Code: |
if (geteuid() != 0) {
fprintf(stderr, "%s: must be superuser.\n", progname);
exit(1);
}
