I dearly wish to use and support this app.
But here's the thing: containers - like so many other mechanisms - suffer from supply-chain risks due to reduced validation to the degree assumed and required compared to, say, good packaging that integrates with the resident source of truth on a given system. Containers, like so many other risky mechanisms that dates back to CPAN or earlier, cannot exist in a secure environment.
For those of us working where we can to minimize repair/recovery work through best practice, Immich cannot be run.
I know there's a homebrew workaround, but given it's external to the dev effort it's a risk that it won't suddenly work as a reliable update resource; and that risk stymies uptake for us.
Now, I know I've suggested there's imperfection in a number of favourite technologies and methods, and that's fine. If downvotes is how you defend these sacred cows, I understand.
