install the dagent on the GSS server. Create a run script job and copy and paste the rh<verion>setup.exe to the job. (you can manually create an ftp directory and copy the source files to that ftp directory)
mount/insert redhat source media. You will have to change the script to reflect the drive letter where the ISO/DVD drive is set to. (in the script it is set to D:) Change "set vmsrcdrv=d:\" to reflect your drive letter (ex. set vmsrcdrv=f:\)
In the \\server\eXpress\samples\ directory create a linux directory. Copy the grub.conf, ks.cfg, and adlagnet.conf.custom (each of the attached files has some custom tokens that will be replaced when the job runs.)
