xhyve system rescue

xhyve-systemrescue.sh

#!/bin/bash
# start up my Arch machine
# for this to work I had to extract kernel & initramfs from the ISO
# which is a surprisingly a pain in the butt on OSX but easy enough
# to find on Google, tldr add 2K of zeroes to the front of the ISO
# then it'll mount just fine

# to make root disk:
# dd if=/dev/zero of=root.img conv=sparse bs=1000000 count=20000

data=/Users/atobey/archbox

# System Rescue seems to need those last 2 params to work in xhyve
# maybe a newer version will fix this?
