Preseed Client

Preseed is the OS deployment technology for Debian and Ubuntu based Linux.
Server commands are run on the Deployment Server. The client configuration commands are run on the Deployment Server, and the client creation commands are run on the host.
The commands are split into three types:
- Server configuration
- Creating OS deployment repositories from the OS installation media (ISOs)
- Client creation
- Creating client VMs.
- Client configuration
- Creating client profiles
- PXE / DHCP / BOOTP configuration
- Install configurations
- Post install scripts
- Creating client profiles
This section refers to the client related commands. For the server related commands refer to the Preseed Server Examples.
For some VM examples of client creation commands refer to either the VirtualBox Examples or VMware Fusion Examples.
List Preseed clients:
./modest.rb --action list --method ps
Create Pressed client:
./modest.rb --action create --name ubuntu1310vm01 --mac 08:00:27:BA:34:7C --arch x86_64 --ip 192.168.1.196 --service ubuntu_13_10_x86_64
