If you're not making changes to the bootloader it's essentially impossible to brick nixos: updates are fully atomic and every change can be rolled back by booting into an old generation.

This combined with the fact that the full source code for the system is contained within a single monorepo that I can checkout and grep through makes NixOS the easiest to understand and most transparent distro I have ever used.

Well, the updates themselves yeah, but not what data they use. You cannot always rollback database upgrades for example, without also having to rollback the data source of the database. In most cases you're right though.

I'm saying this as someone who is a fan of NixOS and use it on all my servers because I tend to forget what I do if I just ssh in and fix stuff. Although I'm on Arch/CachyOS on all other hardware.
