      Always remove notation and you’ll see just how minimal lines of code it is 🙂
      fog.drivers
      [CODE]#!/bin/sh

      machine=dmidecode -s system-product-name; # Gets machine model
      machine=“${machine%”${machine##*[![:space:]]}“}” #Removes Trailing Space
      system64=“/ntfs/Windows/SysWOW64/regedit.exe”; # dirty way to determine if it’s 64bit or not
      if [ -f “$system64” ]; then
      setarch=“x64”
      else
      setarch=“x86”
      fi
      #############################################
      #this is not section necessary needed, it’s just to make the path “human readable”
      #rather than using osid for filepath
      if [ $osid == “5” ]; then
      osn=“Win7”
      elif [ $osid == “6” ]; then

      below creates local folder on imaged pc

      #this can be anywhere you want just remember
      #to make sure it matches throughout!
      mkdir /ntfs/Windows/DRV &>/dev/null;
      echo -n “In Progress”;

      #there’s 3 ways you could handle this,
      #driver cab file, extracted driver files or both
      #so on the server put extracted driver files to match below folder tree
      #i.e. Model Latitude E5410, Windows 7 x86 image would be:
      #/fog/Drivers/Win7/Latitude E5410/x86
      rsync -aqz “/fog/Drivers/$osn/${machine}/$setarch” /ntfs/Windows/DRV &>/dev/null;

      cabextract -d /ntfs/Windows/DRV “/fog/Drivers/$osn/${machine}”/*.CAB &>/dev/null;

      .CAB &>/dev/null;

      #this next bit adds driver location on pc to devicepath in registry (so sysprep uses it to reference)

      remember to make devicepath= match the path you’ve used locally

      #also do not remove %SystemRoot%\inf
      #and to add more locations just use ; in between each location

        this will remove the 2 needed reboots to rename and join domain (if hostname early is not used)

        not much info needed on this pretty self explanatory, uses sed to manipulate unattend.xml to be unique to that machine setting the name and ad details.

        only prereq is that your unattend.xml MUST include:
        <JoinWorkgroup>Workgroup</JoinWorkgroup>
        <Credentials>
        <Password></Password>
        <Username></Username>
        </Credentials>
        <JoinDomain></JoinDomain>
        <MachineObjectOU></MachineObjectOU>

        and other prereq is your ad username should be the new way of just username rather than old domain\username

        nice thing also, it’s not static info and uses fog variables for name and ad details

        one more thing to add, if machine is not set to join ad in fog, it will not add ad details to unattend 🙂

        fog.ad
        [CODE]#!/bin/sh

        hostadpwd=“PasswordtojoinAD”; #only downside to this method- this is the plain ad password
        unattend=“/ntfs/Windows/Panther/unattend.xml”;
        if [ -f “$unattend” ]; then
        dots “Preparing Sysprep File”;
        rm -f /ntfs/Windows/System32/sysprep/unattend.xml;
        echo “Done”;
        dots “Writing Computer Name”;
        sed -i “/ComputerName/s/*/$hostname/g” $unattend
        echo “Done”;
        dots “ComputerName Set To”;
        echo $hostname
        dots “Set PC To Join The Domain”;
        if [ “$addomain” != “” ]; then
        sed -i “/<JoinWorkgroup>/d” $unattend
        sed -i -e “s|<Password></Password>|<Password>${hostadpwd}</Password>|g”
        -e “s|<Username></Username>|<Username>${addomain}\\${aduser}</Username>|g”
        -e “s|<MachineObjectOU></MachineObjectOU>|<MachineObjectOU>${adou}</MachineObjectOU>|g”
        -e “s|<JoinDomain></JoinDomain>|<JoinDomain>${addomain}</JoinDomain>|g” $unattend
        echo “Done”;
        else
        echo “Skipped”;
        fi
        fi[/CODE]

          now this is completely up to you, whatever you want it to do … i use it so that it downloads needed data for unique snapins and i also use it to get switch from fog so that i’m only actually using one script for all our “builds” and the script knows what’s needed by that switch. that way i only ever have to maintain one “snapin”

          i.e. snapin 1 = myscirpt.exe with a switch of /DefaultBuild in my script catches switch so if /DefaultBuild set $somevariable to true then
          if $somevariable = true then
          install these pieces software, add these shortcuts etc etc etc

          a one snapin rules all type scenario 🙂

          [CODE]#!/bin/sh

          snpchk=wget -O - --post-data="mac=${mac}" "http://${web}service/snapcheck.php" 2>/dev/null #checks for snapintask
          if [ “$snpchk” == “1” ]; then
          setupcmd=“/ntfs/Windows/Setup/Scripts/SetupComplete.cmd”;
          mkdir /ntfs/Windows/Setup/Scripts
          #this line below pulls my latest build script from server
          cp /fog/CompleteBuild/CompleteBuild.exe /ntfs/Windows/Setup/Scripts/CompleteBuild.exe &>/dev/null
          #copies lastest setupcomplete.cmd from server
          #which only actually contains one line to execute
          #C:\Windows\Setup\Scripts\CompleteBuild.exe
          cp /fog/CompleteBuild/SetupComplete.cmd $setupcmd #above script
          sloc=“/ntfs/Windows/Setup/Scripts/Node.txt”; # this is just so my above script
          #knows which node to use to run software from (if needed) left in to give you
          #guys ideas…
          echo “$storageip” >> “$sloc”; # writes node ip to the text file
          #next line gets snapin name
          snapname=wget -O - --post-data="mac=${mac}&getSnapnames=1" "http://${web}service/snapcheck.php" 2>/dev/null
          #next gets snapin argument/switch
          snaparg=wget -O - --post-data="mac=${mac}&getSnapargs=1" "http://${web}service/snapcheck.php" 2>/dev/null
          #this next line adds the switch to the setupcomplete.cmd
          # so if switch was /DefaultBuild .cmd line would now look like:
          #C:\Windows\Setup\Scripts\CompleteBuild.exe /DefaultBuild
          #if switch empty just nothing gets added
          sed -i -e “s|$| ${snaparg}|g” $setupcmd

          #this is self explanatory - some of our builds rely on 24GB of map files
          #rather than adding them to the "general" image
          #as it's the select few machines
          #i get fog to add it for me after imaging
          #so if they ever change, just update on server, job done.
          if [ "$snapname" == "MAP Build" -o "$snapname" == "Example Build" -o "$snapname" == "Test Build" ]; then
              dots "Downloading Map Files";
              echo "In Progress";
              rsync -a --info=progress2 "/fog/SnapinData/Map Files" /ntfs
              echo " * Downloading Map Files Completed.";
          fi
          

          else
          echo “No Snapin Task Found - Snapin Setup Skipped”;
          fi[/CODE]

            potentially this means for rename, ad, snapins you wouldn’t need to use fog client… although fog client would be there as a backup if anything failed and i would always recommend still utilizing the FOG Client especially the new one when it comes out, you’d be silly not to!!!

              Hi Lee,
              Can I add in this way the unattend.xml file to the postscripts? If yes, how?
              Thanks

              Corneliu

                You can use these postscripts to alter your unattend file directly.

                What you need to do is know what line needs to be changed to what and make the post scripts mount the partition containing the unattend file and make the adjustments as needed.

                  I thought i would share my own Postdownloadscript. i have a tendency to forget to remove the fog.log file from an image before i upload it, so i made a script to delete it.
                  [CODE]#!/bin/bash
                  #deletes fog.log for Windows 7, 8, or 8.1
                  #Greg Grammon (Junkhacker)

                  #funcs.sh allows us to use the functions that are used in the rest of
                  #fog i.e. “dots” and use the vars already in place i.e. “$part” and “$osid”
                  . /usr/share/fog/lib/funcs.sh;
                  if [ “$osid” == “5” ] || [ “$osid” == “6” ] || [ “$osid” == “7” ]; then
                  mkdir /ntfs 2>/dev/null
                  dots “Mounting Windows File System”;
                  mount.ntfs-3g $part /ntfs 2>/tmp/mntfail
                  mntRet=“$?”;
                  if [ ! “$mntRet” = “0” ]; then
                  echo “Failed”;
                  echo “”;
                  echo -n " * ";
                  cat /tmp/mntfail
                  echo “”;
                  sleep 2;
                  else
                  echo “Done.”;
                  rm /ntfs/fog.log 2>/dev/null
                  echo “”;
                  echo “fog.log deleted”;
                  umount /ntfs

                    This is extremely interesting! Can you explain where in the download process the fog.postdownload script is triggered?
                    I have created those three scripts but I cannot notice anything happening when i run a normal download to a pc but the download process keep looping! it only stops when I remove the script files from the folder…

                      fog.postdownload is triggered/executed by fog.download after the pc has pulled down the image

                        your fog.postdownload is missing: #!/bin/sh

                        also you’ve changed path in fog.drivers to /images (sensible option using existing fileshare!)

                        but your fog.postdownload is still trying to mount /fog so you can hash out/remove that, i can’t remember without checking but /images is still mounted so don’t even need “remount” it.

                              yeah, I was using the already mounted images folder for my drivers. I see now that those other lines are not in use either, thanks

                                I’m attempting to use this in our image deployment to push drivers and am having some trouble that is hopefully not difficult to overcome, I’m just not real script savvy. 😞 I have placed my drivers in the /images/Drivers folder and my fog.postdownload is as follows:

                                
                                #!/bin/sh
                                if [ $osid == "5" -o $osid == "6" -o $osid == "7" ]; then #only handling Win7/8/8.1
                                    clearScreen;
                                    mkdir /ntfs &>/dev/null
                                    ntfs-3g -o force,rw $part /ntfs
                                    # mkdir /fog &>/dev/null
                                    # mount -o nolock,proto=tcp $storageip:/fog/ /fog 
                                    # dots "Mounting Device";
                                    if [ "$?" = "0" ]; then
                                        echo "Done";
                                        . ${postdownpath}fog.drivers 
                                      # . ${postdownpath}fog.ad 
                                      # . ${postdownpath}fog.snapins
                                        umount /ntfs; # unmount when all is done :-)
                                    else
                                        echo "Failed To Mount Device";
                                        sleep 30;
                                    fi
                                fi
                                

                                The computer responds with :

                                ntfs-3g: No mountpoint is specified

                                gives lots of usage instructions and options then

                                Failed to mount device

                                      @gwhitfield as you’re using /images as your driver location you do not need to mount a share as it’s already mounted, so /fog mount is irrelevant to you. as you’re only doing one arch or having both drivers on the image, i’m assuming as you commented it out, make sure your folder layout for drivers matches this for example a Windows 7 build OptiPlex 7010 would be:
                                      “/images/Drivers/Win7/OptiPlex 7010” and all your drivers for the 7010 would be within that folder

                                      Try these and let me know how you get on 🙂

                                        @Lee-Rowlett Seems like I’m very close. The image task completes and I get the following just before the machine restarts. Unfortunately no drivers are copied so the image fails to bootup since there’s no drivers in it:
