I am trying to modify the basic installation environment (ie, what Anaconda runs in) for a customized CentOS distribution.
For the first try, I would just like to modify a few of the splash images.
My initial attempt to do this entailed:
1) Mount images/install.img to a directory ~/img/ 2) Copy all files from img/ to ~/tmpimg/ 3) Modify the splash images 4) mkisofs -o ~/final/install.img 5) cp ~/final/install.img back to my ~/cdroot/ folder and remake the iso.
However, the generated .img in step 4 doesn't even come close to matching the file size from the original install.img (meaning that install.img must be created in some other fashion using compression), and it fails when I boot my iso.
What settings should I be using to make the install.img file? Is there some other technique for modifying CentOS install environments?
