Hi,
When I tried to boot the TAILS 0.6.2 .iso image from USB through GRUB2 ,
I unfortunately found out that it didn't work. Applying the upstream
initramfs-patches didn't do the trick either.
I therefor extracted the initrd image and applied some code from more
recent Debian Live distributions to the scripts/live script to make it
work with the findiso argument. I don't know if this is going to be
useful to anyone, but for those interested, see below GRUB2 menu entry
and diff-patch for scripts/live attached. On my USB-drive, all isos live
in /iso . Patched initrd's live in /boot .
menuentry "T.A.I.L.S 0.6.2" {
savedefault
loopback loop /iso/tails-i386-lenny-0.6.2.iso
echo "Loading kernel.."
linux (loop)/live/vmlinuz boot=live config splash vga=788
live-media=removable nopersistent noprompt=usb keyboard-layouts=us
timezone=local findiso=/iso/tails-i386-lenny-0.6.2.iso
echo "Loading initrd.."
initrd /boot/tails/initrd-mod-0.6.2.gz
Kind regards,
Dirk
