... I finally figured it out!

This is how the wks file should be defined:

> 
> part /boot --source bootimg-partition --ondisk mmcblk1 --fstype=vfat
> --label boot_A --active --align 4096 --size 20 --fsoptions "vfat
> rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro"
> 
> part / --source rootfs --ondisk mmcblk1 --fstype=ext4 --label root_A
> --align 4096 --exclude-path=media/
> part --source rootfs --ondisk mmcblk1 --fstype=ext4 --label root_B --align
> 4096 --exclude-path=media/
> part /media --source rootfs --rootfs-dir=${IMAGE_ROOTFS}/media --size=128M
> --ondisk mmcblk1 --fstype=ext4 --label data --align 4096
> part swap --ondisk mmcblk1 --size 44 --label swap --fstype=swap
> --size=2048M --overhead-factor 1
>

Notice the fact that:

* The mounted point should be excluded from both the root_A and root_B
* The media partition should be sourced on rootfs
* The media partition needs the --rootfs-dir=${IMAGE_ROOTFS}/media options (otherwise the whole rootfs is copied onto /media

Using this in the original method in the recipe above makes it works as expected (if you add the QA_EMPTY_DIRS:remove = "/media"

Thanks
