Besides debian-live and all its users that’s at least Grml (and its derivates) and FAI. I’m maintaining live-initramfs for Grml – so I know the limitations […]

Boot an ISO via Grub2

Monday, May 25th, 2009

You no longer need to extract kernel and initrd from the ISO to be able to boot it using […]
