Simple customization without repacking ISO
Posted: 11 Mar 2010, 13:24
My customization usually consists of setting another default keymap, enabling docache, dhcp and adjusting the boot timeout. To do this I just locate the content of /isolinux/isolinx.cfg in the image file and overwrite it. If isolinux.cfg has a fixed size, and the first line is a comment with a magic string, simple boot option modification can be easily scripted.
