        @george1421 Thing is getting more clear. However, I still need some help. The reason why I need run script every time after I provision the computer is because with different computer I need to download different stuff for the different computer. Let’s say that I have computerA and computerB that I need to provision. How can I possibly specify argument with script, such as, Computer=ComputerA ./script.sh on the home directory?

          @Junkhacker can I run that on the home directory after the computer finishes provisioning? Thanks for jumping in

            @zfeng variables such as the host name are available for use scripting within FOS. this info comes from the host’s profile that gets created when you register a host with FOG.

              @zfeng if you give some more info on what the script is actually doing, we might be able to help you find the best solution faster

                @Junkhacker hostname is part of the script. I also need to do something else such as downloading a particular file with specific variable passed from the argument

                    @Junkhacker the script will install different projects from git repository. everyone of the them needs to have an argument to install specific package on the computer.

                    For now, after I complete the provision part, I basically power up the computer and run Computer=ComputerA ./start.sh on the home directory.

                            @zfeng it sounds like George’s method of creating a file in /etc/init.d on the target disk would work well for you. you can find info on creating postdownload scripts by searching on the forums

                                @zfeng so if you use post download script you could auto set your start script to have the host name preset

                                  @zfeng you could do something like wget -o /root/script.sh <address>/script.sh; echo “Computer=$hostname /root/script.sh” > <drive mount point>/etc/init.d/oneshot.sh

                                  something like that.

                                    @Tom-Elliott The best thing I can do now is to try out that, and see what comes. Let’s say I need provision a linux computer with script Computer=ComputerA ./start.sh on the home directory. Is there any instruction I can try that out?

                                      @Junkhacker where should I specify wget -o /root/script.sh <address>/script.sh; echo “Computer=$hostname /root/script.sh” > <drive mount point>/etc/init.d/oneshot.sh command?

                                        @zfeng in a postdownload script, so that it will run when the imaging process completes but before the imaging task completes

                                          If you search the tutorials FOG forum I have several on creating postdown scipts to install model specific drivers (for windows). The concepts are the same for what you want to do. You will just mount the target computer’s linux root volume. https://forums.fogproject.org/topic/11126/using-fog-postinstall-scripts-for-windows-driver-injection-2017-ed

                                            So you might ask how would you even begin to debug and/or write one of these scripts?

                                            Simple you would go in a create your own bash script in /images/postinstall directory call it something like fog.aws or what ever in there create a simple bash script like

                                            #!/bin/bash
                                            
                                            echo "debug my custom script here. Press Ctrl-C to exit now";
                                            debugPause;
                                            
                                            

                                            Link that script into the master fog.postdownload script. And then schedule a deployment. Before you hit the schedule task button, tick the debug check box. Then pxe boot the target computer. After a few screens of text where you need to clear with the enter key you will be dropped to the FOS Linux command prompt in debug mode. Key in fog to start the master fog script. The master fog script will stop at each break point waiting for you to press the enter key to move to the next debugPause statement. When you see the message you created in your fog.aws script, hit ctrl-C and exit out of the FOG installer script. At this point you will be where your post install script should run. Now you can start developing your post install actions. The fog post install script should be in /images/postinstall on the FOS Linux target computer you can edit with vi or what ever else is on FOS Linux. You can mount the disk partitions all of the contents of the disk image should be on the target computer by now.
