I was annoyed that my solaris system was not registering the hostname I set in /etc/nodename when getting a DHCP address. Turns out nodename is only used locally and not for DHCP (which really doesn’t make sense to me). You have to enable DHCP to register the hostname and set the hostname in a different file. I would expect this task to be an easy thing to find on google, but it took me a while to find it! Maybe my search engine skills aren’t as good as they used to be, but I’ll post this here so others can find it more easily.
