If we copy over a setup script into a VM Template during it's build, we can execute it on first boot up of it's newly created VM and on script completion we can remove the script and hence prevent it from running on subsequent boot ups.
Here are some bash shell script statements that perform some common tasks that may be used in such a script (the value will be placed in a variable for example VAR and it can be used with ${VAR} in the scripts):
Current IP of the container
MYIP=`ifconfig venet0:0 | grep "inet" | cut -d":" -f 2 | cut -d " " -f 1`
Fully Qualified Domain Name of the container
FQDNAME=`hostname`.`dnsdomainname`
