to deploy undead usb from filesystem.squashfs make a MBR dos type usb key with 128m bootable type ef on the first partition, and 8+gb type 83 on the second partition.
run 01 target, run 02 cfdisk, run 03 bootstrap area36 script. then unwrap the squashed area36 into the freshly partitioned usb key. https://code.funtoo.org/bitbucket/users/pnoecker/repos/666/browse

chroot and install grub again.
xorrisofs cd generation via extracted disks.
