Hi,

I'm trying to apply-overlay (test tarball) to a ramdisk inside Android boot image , the image contains the kernel (zImage),  ramdiisk (initrd.img) and a config file (bootimg.cfg).

The Android boot image can be modified using abootimg, for example:

$ abootimg -x boot.img
$ abootimg-extract-unpack-initrd
$ tar -xvzf overlay-5.2.4.tgz -C ramdisk
$ abootimg-extract-pack-initrd
$ abootimg -u boot.img -r init.rd

Currently i can execute a test shell into LXC to make the extraction of the boot image [1][2], the issue i have is that the test overlay tarball (for example: overlay-5.2.4.tgz), isn't available because the creation is handled after the LXC pipeline by deploy action to the target device [3][4].

Any feedback would be appreciate. 

Best regards,
Anibal
