I was wondering if this was Vyatta... it seems it is the community continuation after Broccade ceased development. Used to run this over a decade ago on a 'router' (ThinkCentre Tiny), but eventually went to a Fedora installation a few years back. Might have a look again.
... have to say that the offering is confusing; it is a subscription or a rolling release.
Wondering how much can be automated of the installation/state; would it be possible to use version control? If not, I can see the appeal to suggest Nix over this.
