Wondering if anyone has played with this at all.
I just picked up a couple 32 GB USB flash drives, and am looking to put the 12.3 ISOs on one of the drives configured with grub2 to boot the ISO images directly.
I'm not that particular about which bootloader I use, so if there's a way to hand this off to memdisk or some other boot loader, I'm all ears. :)
I know if I want to put the install DVD ISOs on the drive as distributed, the drive needs to be ext2 rather than vfat.
Many distributions seem to support passing the kernel a "fromiso" or "isofile" parameter so that when the system switches from real mode to the kernel, it can pick up with the ISO file (presumably mounting it via a loop mount). I can't find anything that indicates whether this parameter is enabled in openSUSE or not.
install=hd:/image.iso may work. https://en.opensuse.org/SDB:Linuxrc
I did try a few things out, and was able to (for example) get the initrd to load up, but once that happened, the ISO got yanked out from under the installer, and I ended up in the "simple" installer (ncurses interface where you have to set everything up by hand).
I'm in the process of copying the contents of the ISOs to directories on the drive, and going to look to see if grub2 can chainload the isolinux configurations, but if I could come up with a recipe to do this just by copying the ISOs over, that'd be preferable (that way if I wanted to burn an ISO for someone, I have the file right there).
Thanks!
Jim
