  45           If selected, udhcpd will write a new file with leases every
  46           time a new lease has been accepted, thus eliminating the need

  55           If selected, udhcpd will base its selection of IP address to offer
  56           on the client's hardware address. Otherwise udhcpd uses the next
  57           consecutive free address.
  58
  59           This reduces the frequency of IP address changes for clients
  60           which let their lease expire, and makes consecutive DHCPOFFERS
  61           for the same client to (almost always) contain the same
  62           IP address.

  89           the offered address is really not in use by anyone. The client
  90           will DHCPDECLINE the offer if the address is in use,

  98           If selected, udhcpc will check some options (such as option 12 -
  99           hostname) and if they don't look like valid hostnames
 100           (for example, if they start with dash or contain spaces),

 156           Some buggy DHCP servers send DHCP offer packets with option
 157           field larger than we expect (which might also be considered a
 158           buffer overflow attempt). These packets are normally discarded.
 159           If circumstances beyond your control force you to support such
 160           servers, this may help. The upper limit (924) makes dhcpc accept
 161           even 1500 byte packets (maximum-sized ethernet packets).
 162
 163           This option does not make dhcp[cd] emit non-standard
 164           sized packets.

 166           Known buggy DHCP servers:
 167           3Com OfficeConnect Remote 812 ADSL Router:
 168             seems to confuse maximum allowed UDP packet size with
 169             maximum size of entire IP packet, and sends packets which are
 170             28 bytes too large.
 171           Seednet (ISP) VDSL: sends packets 2 bytes too large.
