For us the 'realpath' command is working fine. The devices do exist at the respective location. Below are the logs from our end for the post-boot scenario and the bootargs. It seems RAUC is trying to look for device '00000000-01' whereas the actual device is '1b325bba-01'. Is there a way we can configure RAUC in userspace to look for device 1b32bba-01 in place of 00000000-01?

this all shows the same issue, RAUC cannot resolve the /dev/disk/by-partuuid/00000000-01 symlink
to the actual device. What does
ls -la /dev/disk/by-partuuid/00000000-01
give you?
What RAUC tries is pretty much the same as
realpath /dev/disk/by-partuuid/00000000-01
does this work calling manually? Maybe it's an issue that you do not have a disk ID set.
Best regards, Enrico
