Is there any way to add another partition after copying the the DVD-1 install image to the pendrive?
I found subchapter 4.3. of the Debian GNU/Linux Installation Guide: "Preparing Files for USB Memory Stick Booting" (https://www.debian.org/releases/jessie/amd64/ch04s03.html.en) and tried to follow some of the instructions--In section 4.3.1. Preparing a USB stick using a hybrid CD or DVD image, I see: <quote> The hybrid image on the stick does not occupy all the storage space, so it may be worth considering using the free space to hold firmware files or packages or any other files of your choice. This could be useful if you have only one stick or just want to keep everything you need on one device. Create a second, FAT partition on the stick, mount the partition and copy or unpack the firmware onto it. For example: # mount /dev/sdX2 /mnt # cd /mnt # tar zxvf /path/to/firmware.tar.gz # cd / # umount /mnt </quote> From the above, I inferred that I should be able to create a 2nd partition after copying the DVD-1 image to the pendrive, but I tried quite a few approaches (that I might describe in a follwup email if someone really wants to know) and I'm beginning to believe it can't be done that way. And, that, instead, you have to follow the procedures in section 4.3.3. "Manually copying files to the USB stick \u2014 the flexible way". I'll characterize those as, generally, partition the USB stick, then add the installer image (and, iiuc, you have to use a different install image than the DVD-1 .iso.) and a different procedure. Am I missing something? PS: Aside: The "instructions" above don't address creating a second FAT partition, only copying stuff to it after it is created--I may send a patch to the maintainer of that document after I fully understand the situation to make it more clear.
