Referring to files in the initial RAM disk

[NiKiZe]

not surprised, as that initial script using intird= is not really loaded as an image, but rather just executed, you can read the sourcecode for the autoboot code to see what is going on there.

if you embed it into your ipxe binary, you can refer to it, there should be examples of that on the forum. (but cant find it, but I think it is EMBED=file1,file2 or similar.)

And since the script provided via initrd= is not in imgstat it also suggest that it wouldn't overwrite those files.

before giving up, I would have at least tried to build with multiple embeded files ans checked what imgstat would give.
