How to extract /system/build.prop from OTA image?

1. Download OTA image from Factory Images for Nexus and Pixel Devices

2. Unpack OTA image with android-ota-extractor. For example, The following command extract "marlin" for Pixel XL version 10.0.0 (QP1A.191005.007.A3, Dec 2019):

$ android-ota-extractor marlin-ota-qp1a.191005.007.a3-23002a57.zip

You will get system.img, it is a Linux ext2 image file.

$ file system.img
system.img: Linux rev 1.0 ext2 filesystem data, UUID=4729639d-b5f2-5cc1-a120-9ac5f788683c (extents) (large files) (huge files)

3. Mount system.img under Linux:

$ sudo mount -o loop,ro system.img /mnt
$ sudo cp /mnt/system/build.prop /tmp/build.prop

Now you get a copy of build.prop in /tmp/build.prop. Feel feel to fork this repo and send a PR to add your build.prop.
