Some examples pointed out above, the big thing is the ‘immutable’ and bit for bit replication to the best of my knowledge.
Ansible is imperativ and applies changes to a starting state. Immutable distros replicate a known state 100%, which is in every respect superior and prevents nasty surprises Immutable distros are 100% reproducible from a config file, which is a big thing for cyber security, building software etc. Debian has too many packages given the amount of contributors they have. The immutable distros are mostly moving to flatpak, which hopefully means that the Distros can focus their energy on a great core experience, and communities like LibreOffice can focus on creating a great flatpak experience.
Nobody says that containers / and/or immutable distros are a good solution for your specific needs and use cases, that’s fine. For me, and after using Silverblue for some time (and btw. containers on multiple occasions), I am looking forward to jumping ship, because I like the user experience, declarative configurations are the logical next step when using Ansible and atomic updates in the backgrounds w/o the problems of package managers are great IMHO.
