removing the state_dir option makes it work with no issues.

Not happening under linux

[mudler]

documentation issue?

I also ran into this on mac and it seems like there is a problem writing to the bind mount for the flag

 -v "$PWD"/build:/tmp/auroraboot

I assume the reason why removing the state dir config works is because it writes to /tmp/ instead by default which is not in the bind mount directory.

As an alternative that worked for me, you can create a docker volume to store data for reuse across builds like -v auroraboot-tmp:/tmp/auroraboot
