here is the boot.img from the Amazon Fire HD 10, 2017, firmware version update-kindle-40.6.0.5_user_605485120.bin. Thank you so much. Let me know if you need anything else. Just extract the .img from the zip.

i extract all of bin when i unpacking system.img,i find that it has a make_ext4fs and ext4analyse.exe，i use this word'echo ext4analyse.exe folder>**.txt'，and then the txt a little like file_contexts,and i use CMD to use make_ext4fs,use file_contexts built by Classy Kitchen,it working,i think that just need find out ext4analyse how to build a context file,maybe it is a project in github,i see Classy Kitchen thanks for a project in github which called EXT4,cubinator's project

Classy Kitchen build context above 300kb，in etc just 28kb，i nerver use context in etc,and ext4_analyser.exe can save fs_config,make_ext4fs need that,and it have another file is busybox,maybe he use busybox grep to extract fs_config and context

u need know that imgextractor can not extract after 8.0,it means so much big file was brake down,u can test it,and fs_config is incomplete,so after 8.0 i first use imgextractor extract system.img and use 7zip extract the big file,i extract all of Classy Kithen binary,https://d rive.go ogle.com/open?id=1oiwVUl d4r7u6rqsdzRvP2O7oHMBLWLBD

Hi friend.
i found the .py code:

#!/usr/bin/env python3

import ext4

if not exists:
print("Error: input file " f"[{args.ext4_image}]" " was not found")
sys.exit(1)

file = open(args.ext4_image, "rb")
volume = ext4.Volume(file)
