This thread is going to be a no nonsense tutorial rehashing other posts if yesteryear.
In this tutorial we will create 2 new FOG postinstall scripts and update the master fog postinstall script to call our new scripts.
fog.custominstall
- Create the following file named
fog.custominstall
in the following path on the FOG server /images/postdownloadscripts
.
- Copy the content into that newly created file

- Save and exit your text editor.
- Make the script executable with
chmod 755 /images/postdownloadscripts/fog.copydrivers
fog.updateunattend
This section is optional. You do not need to use this script if you do not need to patch or amend your unattend.xml file. If you want dynamic updates to your unattend file then you can use this section of code. Remember to uncomment the call to this script in the fog.custominstall
script.
- Create the following file named
fog.updateunattend
in the following path on the FOG server /images/postdownloadscripts
.
- Copy the content into that newly created file:
#!/bin/bash
hostadpwd="ADPASSWDHERRE"; #only downside to this method- this is the plain ad password
unattends=$(find /ntfs/ -iname "unattend.xml")
for unattend in $unattends; do
[[ ! -f $unattend ]] && return
dots "Preparing Sysprep File"
#rm -f /ntfs/Windows/System32/sysprep/unattend.xml >/dev/null 2>&1
#if [[ ! $? -eq 0 ]]; then
#echo "Failed"
#debugPause
#handleError "Failed to remove original unattend file"
#fi
echo "Done"
debugPause
dots "Writing Computer Name to $unattend"
sed -i "/ComputerName/s/*/$hostname/g" $unattend >/dev/null 2>&1
if [[ ! $? -eq 0 ]]; then
echo "Failed"
debugPause
handleError "Failed to update originating unattend file"
fi
echo "Done"
echo "ComputerName set to $hostname in $unattend"
debugPause
[[ -z $addomain ]] && continue
dots "Set PC to join the domain"
sed -i "/<JoinWorkgroup>/d" $unattend >/dev/null 2>&1
if [[ ! $? -eq 0 ]]; then
echo "Failed"
debugPause
handleError "Failed to remove the Workgroup setter"
fi

if [[ ! $? -eq 0 ]]; then
echo "Failed"
debugPause
handleError "Failed to update user, pass, ou, and domain setter"
fi
echo "Done"
debugPause
done
- Save and exit your text editor.
- Make the script executable with
chmod 755 /images/postdownloadscripts/fog.updateunattend
fog.postdownload
The last bit of magic we need to do is update the FOG supplied script called fog.postdownload
to call our custom script fog.custominstall
- Insert at the bottom of the
fog.postdownload
script this line.
. ${postdownpath}/fog.custominstall
- Save and exit your text editor.
Driver repository structure
For this process to work you must setup your driver library on the fog server in a certain fashion.
On your fog server create the drivers directory under the images directory with:
md /images/drivers
Below the /images/drivers directory you will create a directory per machine name (that exactly matches what comes from smbios using this command for Dell computers dmidecode -s system-product-name
Hint: You can also find the system product name by reviewing the inventoried system in the FOG WebGui.
The structure should be built to match the variables used in the fog.drivers script.
/images
├─/drivers
├─$machine
├─$osn
└─$arch
or translated into real values (note that the space has been removed for “Optiplex 7040” to this Optiplex7040. There is a clean up line above that removes spaces in the product name. While linux supports spaces in path names (like Windows) its bad practice to use them because some utilities will see the space as a parameter delimiter.
/images
├─/drivers
├─Optiplex7040
├─win7
└─x86
└─x64
├─win10
└─x64
├─Optiplex7050
...
Unattend.xml
For WIN10 you must update the unattend.xml file to include this section. This is an example for the amd64 arch.
