[Nix-dev] vagrant-nixos-plugin

[zimbatm]

Hello,

Thanks for the pointer Charles.

I had a look at the Vagrant source code and support for generating the
/etc/nixos/vagrant-hostname.nix and /etc/nixos/vagrant-network.nix file has
been stable since release v1.6.4. What I didn’t see is any invocation
to nixos-rebuild
switch so I’m not really sure how the configuration is applied. The
simplest way to apply those changes would be to add a shell provisioner.
One downside of that approach is that vagrant provision has to be called
explicitly after config changes, cycling the machine power isn’t enough.

config.provisioner :shell, inline: "nixos-rebuild switch"

It wasn’t necessarily clear if the main vagrant project would accept such
os-specific provisioner so in the end I just removed the duplicate
functionality in the vagrant-nixos-plugin plugin.

Release v0.1.1 is a much cleaner version of the plugin and does just the
provisioning bits.

One notable addition is that just adding the following statement inside of
the configuration is enough to provision hostname or networking changes
(but vagrant provision still needs to be called explicitly):

config.provisioner :nixos
