Hello Matt:<br>
<br>
If you do not need the client to support DNS updates, you can
compile it out. To do so you need to:<br>
<br>
1. Undefine NSUPDATE (comment it out) in includes/site.<br>
2. dhclient_ddns_cb_free(), needs to be wrapped with NSUPDATE
conditional compilation. <br>
<br>
Rebuild.<br>
<br>
I have attached a diff, containing these changes. The resulting
client is notably smaller. Please note that, these changes have<br>
not been tested and are use-at-your-own-risk. <br>
<br>
Sincerely,<br>
<br>
