Berryboot - Add OS - Squashfs of Volumio

Volumio Information

Volumio Version: volumio-2.873-2021-02-19-pi.img
Hardware: Raspberry Pi 3 Model B+
DAC: Topping D10s

Hi together
Volumio doesn’t support Amazon Music HD. I’m looking to combine it with Volumio: on the same (Raspberry) device would have liked install Volumio with another system which gives i.e. Firefox to connect to Amazon Music HD, attached via Topping 10s DAC to my active loudspeakers.

To add on berryboot I was able to create a corresponding Squashfs of Volumio’s Raspberry image on Ubuntu 20.04, obviously with no error as you may see below:

george@george-NUC8i5BEH:~/Schreibtisch/Berryconv/BerryConverter-master$ chmod 755

george@george-NUC8i5BEH:~/Schreibtisch/Berryconv/BerryConverter-master$ ./ volumio-2.873-2021-02-19-pi.img volumio-2.873-2021-02-19-piB.img

Booting up, there is an error:

unable to locate or execute sbin/init user/lib/systemend/systemend /init inside volumio-2.873-2021-02-19-piB.img (...B=name of the converted file).

Is there any help possible, hopefully not too complicated, because I am an old man with only user knowledge of Ubuntu?

Hoping to hear from you is

With respect, forget the idea of adding Volumio as a squashfs from the 2nd partition, there is a lot more to that.
Volumio was setup as a standalone system, with it own OS, fixed boot partition and a combination of RO (squashfs) and RW using overlayfs. On top of that, the partition structure is fixed, you cannot change that, updating would never work.
There is a plugin (please search) which could help, but only for a PI.

I thank you for your quick, resolute and competent reaction. - I will give up - which brings me back my sleep.

What exactly do you mean with the plug-in for Raspi? Would you mind please telling me?

Thanks a lot (mille grazie)
