6 things you probably want to do after Solaris 10 installation

1. Set BASH as default shell for root:
This is first thing I really do! Because bash has multiple advantages for day to day use and scripting too, over other shells.
For this you can simply edit /etc/passwd file and change the shell from very first line.
By default it is /sbin/sh, you can change it to /bin/bash

2. Change the hostname from "unknown"
To change the hostname temporarily:
 hostname SERVER01  
To change the hostname so that it is persistent across reboots:
 echo SERVER01 > /etc/nodename  
However, the changed hostname is re-set when you run sys-unconfig command to reset the configuration of the system.

3. Disable GUI Login:
 /usr/dt/bin/dtconfig -d  
For more, see here about disabling and enabling GUI login in Solaris

4. Configure loghost:
You might get messages such as "loghost could not be resolved.". To be able to resolve loghost you must configure DNS Server or you can add entry in /etc/hosts such as "  loghost".

5. Disable sendmail:
You can disable sendmail by issuing a simple command,
 svcadm disable sendmail  
Hmm... not everybody uses sendmail... 

6. Set PS1 variable (This is only for people using BASH):
It is solely user's choice to set this variable. Solaris has it as PS1='\s-\v\$ ' by default.
However, I set it as PS1="$LOGNAME@$HOSTNAME# " so that it will be displayed as:
 root@SERVER01# _
