Hi Christian,

Sorry for the late reply.

I built the rootfs image by poky with "read-only-rootfs" option like following URL.
<https://www.yoctoproject.org/docs/current/mega-manual/mega-manual.html#creating-the-root-filesystem>

I think that the temporary storage directories were mounted as tmpfs as follows:

    root at beaglebone:~# df -T

    /dev/root      ext4        135221 75902     49409  61% /

I checked this by tune2fs, and it was correct.

    After the 1st boot:

        root at beaglebone:~# tune2fs -l /dev/mmcblk1p2 | grep "Mount count"
        Mount count:              1

        root at beaglebone:~# hexdump -C -n 2048 /dev/mmcblk1p2 | grep 430
        00000430  81 43 6d 38 01 00 ff ff  53 ef 01 00 01 00 00 00  |.Cm8....S.......|

    After the 2nd boot:

        root at beaglebone:~# tune2fs -l /dev/mmcblk1p2 | grep "Mount count"
        Mount count:              2

        root at beaglebone:~# hexdump -C -n 2048 /dev/mmcblk1p2 | grep 430
        00000430  f4 a4 90 5c 02 00 ff ff  53 ef 01 00 01 00 00 00  |...\....S.......|

    After the 3rd boot:

        root at beaglebone:~# tune2fs -l /dev/mmcblk1p2 | grep "Mount count"
        Mount count:              3

        root at beaglebone:~# hexdump -C -n 2048 /dev/mmcblk1p2 | grep 430
        00000430  63 a6 90 5c 03 00 ff ff  53 ef 01 00 01 00 00 00  |c..\....S.......|

BTW, the values of "Last mount time", "Last write time" and "Lifetime writes" were also changed.

I'm concerned that if the partition which is set to rdiffbase is changed as above,
the binary delta update will be done correctly or not.

Thank you for the detailed explanation. 
I was thinking the same way, too.

The exact steps I performed are as follows:

     1. Build rootfs image as v1 by poky by reference to the following article:
        <https://mkrak.org/2018/01/26/updating-embedded-linux-devices-part2/>
     2. Boot BeagleBone Black (BBB) from microSD
     3. Write "core-image-full-cmdline-beaglebone.wic" to /dev/mmcblk1 (eMMC) on BBB
     4. Write "core-image-full-cmdline-beaglebone.ext4" to /dev/mmcblk1p2
     5. Make /dev/mmcblk1p3 partition by fdisk and copy /dev/mmcblk1p2 to /dev/mmcblk1p3
     6. Shutdown BBB and boot from /dev/mmcblk1p3
     7. Add a change to the recipe of poky and rebuild rootfs image as v2
     8. Make a delta image from v1 and v2 by rdiff command
     9. Make swu image from attached sw-description, emmcsetup.lua, and the delta image
    10. Access http://[IP address of BBB]:8080/ by Web browser and upload the above swu image
        (After the update is finished, It reboots automatically)
    11. Check the update is done correctly
        (It boots from /dev/mmcblk1p2 and the rootfs image version is v2)
    12. Do the step of No.10 to update the rootfs image on /dev/mmcblk1p3 to v2
    13. After updating and rebooting, BBB is booted from /dev/mmcblk1p3 and
        the rootfs image version is v2, but the ext4 warning message is shown

If you need more detailed steps, please let me know.

To tell the truth, at first, I set the different partition to "device" and "rdiffbase" field at sw-description.
If "/dev/mmcblk1p2" was set to "device", I set "/dev/mmcblk1p3" to "rdiffbase" -- and vice versa.
When I used this sw-description, the ext4 warning message was shown at the step of No.11.

The kernel version is v4.12.28, but I think that it is no relation of this issue...
