All the newly built stable images (announcement pending) seem to have `bullseye-security` listed in the sources.list. So, there is no problem there.

It is also best if users use `bullseye` everywhere in the sources.list instead of `stable` to allow FreedomBox to automatically upgrade to next stable release bookworm in 2 years in controlled manner. A typical sources.list file should look like:

```auto
deb http://deb.debian.org/debian bullseye main
deb-src http://deb.debian.org/debian bullseye main

deb http://deb.debian.org/debian bullseye-updates main
deb-src http://deb.debian.org/debian bullseye-updates main

deb http://security.debian.org/debian-security/ bullseye-security main
deb-src http://security.debian.org/debian-security/ bullseye-security main

deb http://deb.debian.org/debian bullseye-backports main
deb-src http://deb.debian.org/debian bullseye-backports main

```
