I realized i can likely make a live USB with what i've got using the make
live device script, so i'm giving that a shot. But I also got a partial
success trying to boot directly from the ISO. However it seemed to get hung
up somewhere, so i'm guessing i'm not passing the correct boot options.
this is what i have in my /etc/grub.d/40_custom file...
menuentry "PureDyne DVD ISO on /dev/sdb6" {
insmod ext2
set root=(hd1,6)
search --fs-uuid --set d3afdd1-045a-490f-b7ba-86c0c2d8c500
loopback loop
(hd1,6)/home/gcentauri/Downloads/puredyne-911-carrot_and_coriander-DVD-i386.iso
linux (loop)/live/vmlinuz boot=live
iso-scan/filename=/home/gcentauri/Downloads/puredyne-911-carrot_and_coriander-DVD-i386.iso
quiet splash --
initrd (loop)/live/initrd.img
}
with the command like that it seemed to hang, but the quiet option just kept
it at the grub screen. i deleted that option and the search --fs-uuid
thing... and maybe the set root one? perhaps i should just try removing
quiet by itself and seeing what happens.
it did seem to be trying to boot however, so thats something.
