Alas, the maintainers declined to act on my RFE. So I was forced to find
a way to make the transfer. I couldn't simply use dd to copy the DVD ISO
image to an 8GB thumb drive because bootable CDs/DVDs use the Eltorido
method rather than GRUB's two phases.
So... here's the step-by-step process:
1. # fdisk /dev/sdc <-- make 1 primary partition with default start/end, bootable, type 83
2. # mke2fs -L Fedora-14-multi /dev/sdc1 <-- make ext2 filesystem
3. # tune2fs -c 0 /dev/sdc1 <-- disable autofsck
4. Remove & reinsert thumb drive to automount at /media/Fedora-14-multi
5. # mount -t iso9660 -o loop /pathto/Fedora-14-Live-multi.iso /tmp
6. # cp -dR /tmp /media/Fedora-14-multi/
7. # cat 'hd0<Ctrl-V><I>/dev/sda' > /media/Fedora-14-multi/boot/grub/device.map
8. # cat 'hd2<Ctrl-V><I>/dev/sdc' >> /media/Fedora-14-multi/boot/grub/device.map
9. # grub-install --root-directory=/media/Fedora-14-multi --no-floppy '(hd2)'
(1) I have two "real" hard drives in the uber-laptop used to work out
this process. When inserted, a USB thumb drive is assigned /dev/sdc. On
your system it could be /dev/sdb or even /dev/sdd. Adapt.
(2) <Ctrl-V><I> inserts a <tab> character
Now I can plug in this thumb drive and use it to boot to a GRUB menu
offering me 32-bit or 64-bit versions of the Fedora 14 GNOME, KDE, LXDE,
and XFCE live CDs. Even if I don't have an optical drive.
