Er...It's my fault not explaining my demands clearly...
I want to use cfengine3 to set my hostname which contains a part of the ip
address...
The only way i can find is using shell script to "grep" it from the output
of "ifconfig", and someone tells me in cfengine2 there is a builtin variable
so i want to know if there is also a simple way in cfengine3?
