OK, so I took out the mSATA SSD, dd'ed the combined-squashfs image to it, put it back into the APU2 and ran sysupgrade. It lost its settings again. After that, I set up the configuration manually, thinking maybe there was something wrong with the configuration backup; unfortunately, just the same happens.
Seems the overlay is F2FS, but I'm not seeing any storage related error messages in dmesg:
