Hi Ernestas,

Ehm....and what is the difference with the commit 3d6f2ac, that I
already merged ?

https://github.com/sbabic/swugenerator/commit/3d6f2acc6056a2be3fcf5a6b79419683f634b142

Best regards,
Stefano Babic

Hey, Stefano,

That commit is for _decrypted_ size, while this patch is for
_decompressed_ size. :)

Ah ok, my fault. I will merge it. It is really required just for UBI
volumes, but it should not hurt if it is always set.

Regards,
Stefano

Ah, I see, UBI volumes was exactly my use case, so I didn’t investigate
further.

[Stefano Babic]

Maybe for compatibility reason (the property is added just in this
case), you should first check if the type is UBI, and add it just in
that case.

Best regards,
Stefano
