Hi, All: I'm trying to add a preseed.cfg to USB install media created with one of the isohybrid images.
I follow the instructions using dd to transfer the image to the USB drive, and all goes well. I can install, and it does so nicely. As I try to copy a preseed.cfg file *to* the USB drive after dd the isohybrid image, it tells me variously that it's a read-only file system (ISO9660), or that it is write protected. FWIW, it's a Verbatim thumb drive with 1 gig of capacity, of which (naturally) about 225gb is in use. Anyone ever started from the netinst ISO image and added a preseed.cfg file?
