Hi @slwyts,
Packing system.img is not supported yet.

[slwyts]

When can it be realized? Or you switch to ext4 to mount the image, and sign after modification

[cfig]

It will be done with low priority.
"Or you switch to ext4 to mount the image, and sign after modification" => I've been thinking about this solution too. Needs some tests.

[cfig]

A new commit has been submitted to support sparsed ext4 (or raw ext4) images.
#133

I tested with vendor_dlkm.img, this should also work for other ext4 based images.

[cfig]

Special note: it only works for dynamic partitioned system.img., and vbmeta.img should also be updated together.
