Solved

osdiskpart=“/dev/sda2”;

mkdir /ntfs 2>/dev/null

mount.ntfs-3g “${osdiskpart}” /ntfs 2>/tmp/mntfail

mntRet=“$?”;
if [ ! “$mntRet” = “0” ]; then
echo “Failed to mount C:”;
cat /tmp/mntfail;
sleep 12;
exit 1;
fi

unattendfile=“/ntfs/Windows/Panther/unattend.xml”;
sed -i -e “s#<ComputerName>([^<][^<]*)</ComputerName>#<ComputerName>$hostname</ComputerName>#gi” $unattendfile

Of course this assumes that /dev/sda2 is the windows main partition.

script is working but something is wrong

it seems that fog cannot find or access to the unattend file (autounattend.xml)

i have read in a @george1421 post a special bloc like :
####################

windows 10/11

osdiskpart=“/dev/sda2”;

mkdir /ntfs 2>/dev/null

mount.ntfs-3g “${osdiskpart}” /ntfs 2>/tmp/mntfail

mntRet=“$?”;
if [ ! “$mntRet” = “0” ]; then
echo “Failed to mount C:”;
cat /tmp/mntfail;
sleep 12;
exit 1;
fi

Should i put this in my fog.postdownload juste before my sed command or am wrong and another way exists ?

You could test it by creating a simple example of the file and running the sed statement itself. Ultimately, though, it should work properly.

in /images/postdownloadscripts/ :

fog.postdownload (default file)
fog.custominstall

1. in fog.postdownload (i call the created file)

. ${postdownpath}/fog.custominstall

2. in fog.custominstall (unattend declaration & sed command)

unattendfile=“/ntfs/Windows/Panther/unattend.xml”;

sed -i -e “s#<ComputerName>([^<][^<]*)</ComputerName>#<ComputerName>$hostname</ComputerName>#gi” $unatendfile

Should be right ?

These postdownload scripts are customizable to your hearts content, so yes it’s possible, technically, but as far as getting support for your own scripts, we’ll try, but it’s still all best case.

The FOG Client will do so in a well standardized method but if you don’t want to use that, that’s perfectly fine as well.

We will still attempt to assist as required.

Thank you,

moderator @george1421 put an important information about possibility to update unattend file. So it would be possible to use Fog variable into the file.
If it works like he says so it means that i don t need Fog client install on my golden image and the Setup complete cmd.

If i understand, first in put in a post download script (/images/postdownloadscripts/myfogscript.sh)

This :

Unattend.xml path (note the case specifics in the file name and path)

unattendfile=“/ntfs/Windows/Panther/unattend.xml”;

And this :

sed -i -e “s#<ComputerName>([^<][^<]*)</ComputerName>#<ComputerName>$hostname</ComputerName>#gi” $unatendfile

So it means that it could may be possible to change hostname without fog client on machine right?

I would have prefered a solution without the Fog client on machine but it seems impossible with sysprep stape.

Thx a lot for your help!!

If you are wanting to install the FOG client on your golden image, make sure that you disable the FOGService in the windows services. You can use this link for reference of how to do this correctly with sysprep. https://wiki.fogproject.org/wiki/index.php/FOG_Client#FOG_Client_with_Sysprep

I would also recommend you upgrade your FOG install to the latest stable release 1.5.10.1629 since there have been a lot of improvements done since version 1.5.9.
