Im trying to find out, why z4h is starting in recovery mode.

Its a freshly installed system without any changes other than copying my public key into .ssh/authorized_keys

Thats the system im talking about:

I already found a hint of adding setopt xtrace to .zshrc but that did not result in any output that could give a hint to the actual error causing z4h to start in recovery mode.

What options do i have to find the cause?
