Introduction

Bento 1.0.0 is alive!

Compared to the previous news, it received

bento is now a single script, easy to package and add to $PATH. Before that it was a set of scripts with a shared shell files with functions in it, not very practical…
the hosts directory can contain directories with flakes in it, that may contain multiple hosts, it’s now handled. If there is no flake in it, then the machine is named after the directory name
bento supports rollbacks, if something is wrong during the deployment then the previous system is roll backed
enhancement to the status output when you don't have a flaked system, as build are not reproducible (without efforts) we can't really compare local and remote builds

network measurements shown that polling for configuration changes costs 5.1 kB IN and OUT
many checks has been added when something is going wrong

On step

It's a huge milestone for me, I thought it would be too much work to get there, but in one week and 441 lines of shell, bento is a real thing.
