Hello Albert, You can use initramfs to accomplish all of your tasks. 1) Take a look at meta/recipes-core/initrdscripts/initramfs-live-boot_1.0.bb as a starting point, it provides ability to mount rootfs with overlay fs in ram (but all the modifications to rootfs are lost after reboot); You'll have to write your own implementation where other partition or file is used as an overlay; 2) You will have to create web interface yourself; Typically you have to upload update files using web ui to some location which is accessible from initramfs; then from the initramfs script check if there are update files available, validate them, and replace existing initrd, vmlinuz rootfs.img, remove update files and reboot; 3) I don't think that there is such functionality out of the box, because it is very application-specific, but you can write your own implementation; Again, this can be done from the initramfs script, just recreate partition or file with overlay, this will return rootfs to its initial state;
Probably you will have to re-partition your CF card for your specific needs, take a look at meta-raspberrypi/classes/sdcard_image-rpi.bbclass. BR, Maxim.
