| # The interface that udhcpd will use |

| # The maximum number of leases (includes addresses reserved |

| # The amount of time that an IP will be reserved (leased to nobody) |

| # The amount of time that an IP will be reserved |

| # The location of the pid file |

| # The location of the leases file |

| # The time period at which udhcpd will write out leases file. |

| # The following are BOOTP specific options |
| # next server to use in bootstrap |
| #siaddr 192.168.0.22 # default: 0.0.0.0 (none) |
| # tftp server name |
| #sname zorak # default: none |
| # tftp file to download (e.g. kernel image) |
| #boot_file /var/nfs_root # default: none |
| |
| # NOTE: "boot_file FILE" and "opt bootfile FILE" are conceptually the same, |
| # but "boot_file" goes into BOOTP-defined fixed-size field in the packet, |
| # whereas "opt bootfile" goes into DHCP option 0x43. |
| # Same for "sname HOST" and "opt tftp HOST". |

| # The remainder of options are DHCP options and can be specified with the |
| # keyword 'opt' or 'option'. If an option can take multiple items, such |
