This breaks my setup where I have U-boot provided more size of

decrease initramfs compressed image without taking care of bootloader.
The proper solution is to do this if we sure that we didn't get enough

OK, thanks. Maybe David can suggest a fix - I'll queue up a revert
I don't really understand the failure. Why does an oversized initramfs
cause unpack_to_rootfs() to fail?
In my case I have got "Junk in compressed archive". I don't know (I
would check if needed) which exact condition I got since there are
three places with this message.
Well that's a plain irritating screwup right there. Could someone
