Error installing yunohost in a custom liveCD

My YunoHost server

Hardware:
Cubic wizard in order to decompress the official livecd of debian11, then copy in a folder and open a chrooted terminal in the livecd envirnment

the error is:

Setting up yunohost (11.0.10.2) ...
System has not been booted with systemd as init system (PID 1). Can't operate.
Failed to connect to bus: Host is down
dpkg: error processing package yunohost (--configure):
 installed yunohost package post-installation script subprocess returned error exit status 1
Errors were encountered while processing:
 yunohost
E: Sub-process /usr/bin/dpkg returned an error code (1)

I am looking for a way to “trick” the yunohost installer so that it does not realize that it is not in a real environment
any trick?
Cheers
Max
