rsync: [generator] failed to set permissions on "/media/ziomario/isoarm/aosp/vendor-rw/bin/expand": Operation not supported (95)

Hello.

I'm trying to create an AOSP image that I want to virtualize on the Nvidia Jetson Nano with qemu-kvm. To to this,I have tried to clone the repo from this page :

https://github.com/antmicro/kvm-aosp-jetson-nano

According with the tutorial,these are the commands that I have issued before to get the error :

going forward with the commands,this is what happened :

root@ziomario-Z390-AORUS-PRO:/media/ziomario/isoarm/aosp# sudo mount system-rw.img
system-rw

root@ziomario-Z390-AORUS-PRO:/media/ziomario/isoarm/aosp# sudo mount out/target/product/generic_arm64/system.img system-ro -o ro

you can see the error reported by this command :

root@ziomario-Z390-AORUS-PRO:/media/ziomario/isoarm/aosp# sudo rsync -avxHAX system-r{o,w}/
sending incremental file list

and you can see the error reported by this command :

rsync -avxHAX vendor-r{o,w}/

this is not a bug. It was a file permission problem.

[Christian Ehrhardt  (paelzer)]

IIRC the discussions that happened on this topic already asked for the target file system.
I see you mount the image there
  root@ziomario-Z390-AORUS-PRO:/media/ziomario/isoarm/aosp# sudo mount system-rw.img system-rw

ut fromt he log it is unclear what Filesystem that is, and the rsync command asks it to retain ownership/permissions which some filesystems can't store.

Hence after mounting your image, could you check as what this is effectively mounted?
Maybe for a start just post:
 $ mount | grep system

Once you know that you very likely will be able to break it down to a much simpler case.
For example take "one file" with "this set of ownership/permissions" and copy it from "e.g. ext4" to an image that is "unknown filesystem".
Which would be much much easier than having everyone try to setup aosp and such.

luckily copying the repo in my desktop instead of a different disk make disappeared the rsync errors.
