i wanted to create a custom minimal install boot usb drive, I noticed on the RHEL ES4 amd64 cds they have both x86_64.rpm files and also i386.rpm files, to make the bootable usb smaller i wanted to know if i needed the i386.rpm packages. I already have my ks.cfg, and know exactly which packages i need to install but i wasnt sure if i needed the i386.rpms also.
