Loong time no hear 
Maybe so saw already that your sos box did receive an updated sos version and did so also in the last years from time to time.
I was working a lot on sos the last weeks. Mainly to move towards Trixie, which is working almost nice but shortly before everything was fixed, I stopped (in fact yesterday)…
Why? I saw, that the integration of syncosync in the raspi was in some extend quite hackish: the system is tuned exactly for the needs of sos regarding passwords, network setup and so on. We want to clean this up, and at the same time we really want to have only one additional feature on the sos box to provide the perfect disaster backup: a password safe.
The idea is to go with vaultwarden for this one and therefore this leads also into docker and this leads into also running syncosync in docker.
This will be the work of the next weeks and months, the next full install image will therefore be Trixie with dockerized stuff and the plan - also for the sake of ourselves as we are all using sos over the last years without any flaws - is to work on the same disk layout as before.
So stay tuned, and keep an eye on the discussions which will start in gitlab, if you want to join them you are welcome.
Cheers
Steve
