Postdownload Scripts

[SHerder]

I’m curious if there’s a way to have the postdownload scripts only run for certain images and not all of them.

No, it’s a run on everything, or not. Though you can add checks in your post download script to only run commands if the image is a certain name.

For example, something like:

case $img in
    ImageNameForDoingStuff)
        # do stuff for this image.
        ;;
    *)
        # do stuff for everything else, or return.
        ;;
esac

Like @Tom-Elliott said, the initial postdownload script always runs. However, you can use CASE or IF statements to either call a function or open another script. Here is my current postdownload script that I got from one of @george1421 and his wonderful driver injection scripts found here

#!/bin/bash
. /usr/share/fog/lib/funcs.sh
[[ -z $postdownpath ]] && postdownpath="/images/postdownloadscripts/"
if [ $img == "Win7BaseVM" ] || [ $img == "Win10BaseVM" ] ; then
	case $osid in
	    5|6|7|9)
	        clear
	        [[ ! -d /ntfs ]] && mkdir -p /ntfs
	        getHardDisk
	        if [[ -z $hd ]]; then
	            handleError "Could not find hdd to use"
	        fi
	        getPartitions $hd
	        for part in $parts; do
	            umount /ntfs >/dev/null 2>&1
	            fsTypeSetting "$part"
	            case $fstype in
	                ntfs)
	                    dots "Testing partition $part"
	                    ntfs-3g -o force,rw $part /ntfs
	                    ntfsstatus="$?"
	                    if [[ ! $ntfsstatus -eq 0 ]]; then
	                        echo "Skipped"
	                        continue
	                    fi
	                    if [[ ! -d /ntfs/windows && ! -d /ntfs/Windows && ! -d /ntfs/WINDOWS ]]; then
	                        echo "Not found"
	                        umount /ntf >/dev/null 2>&1
	                        continue
	                    fi
	                    echo "Success"
	                    break
	                    ;;
	                *)
	                    echo " * Partition $part not NTFS filesystem"
	                    ;;
	            esac
	        done
	        if [[ ! $ntfsstatus -eq 0 ]]; then
	            echo "Failed"
	            debugPause
	            handleError "Failed to mount $part ($0)\n    Args: $*"
	        fi
	        echo "Done"
	        debugPause
	        . ${postdownpath}fog.deletelog
	        . ${postdownpath}fog.drivers
	        #. ${postdownpath}fog.ad
	        umount /ntfs
	        ;;
	    *)
	        echo "Non-Windows Deployment"
	        debugPause
	        return
	        ;;
	esac
fi

You can see that I have an if statement at the beginning to only run his driver injection script if the image name is one of my golden image VM’s.
