Changing the hostname in Solaris 10

Changing the hostname of a system in Solaris 10 is pretty much the same as in Solaris 9. I'm posting this because I had to look through several pages and piece this process together myself when looking for how to do it.

Follow these steps to rename the system:

Change the name in /etc/nodename.
Change the name in /etc/hostname.xl0 (where xl0 is the name of your network interface)
Change the name in /etc/hosts.
Run the command: hostname new_hostname

EDIT: Thanks to eon who submited this information. The file /etc/dumpadm.conf should also be edited and the directory where it puts the dumps must be created. See his comment below.

If anyone knows of any other common files where the hostname is stored, please let us know using the comment system below.
