不需要费那个事的，安装 lupin-casper 就可以得到能够引导 iso 的 initrd，19~21楼我已经说得很清楚了。

# You should mount the squashfs image first
loopback loop /imagepath
# then you can get files from (loop) device
set root=(loop)
# Do some "init" work
set settings="noinitrd"
# "boot=casper" is just let initrd execuate /script/casper
# load kernel
linux /vmlinuz init=/sbin/init ${settings}
# Or you can load another kernel
# linux (hd0,1)/filepath ${settings}
# And you can boot
# Good luck
