*Building blocks for self-hosting with battery included.*

SHB's (Self Host Blocks) goal is to provide a lower entry-bar for self-hosting. I intend to achieve
this by providing opinionated building blocks fitting together to self-host a wide range of
services. Also, the design will be extendable to allow users to add services not provided by SHB.

## Tips

### Deploy

```bash
$ nix run nixpkgs#colmena -- apply
```

### Diff changes

```bash
$ nix run nixpkgs#colmena -- build
...
Built "/nix/store/yyw9rgn8v5jrn4657vwpg01ydq0hazgx-nixos-system-baryum-23.11pre-git"

# Make some changes

$ nix run nixpkgs#colmena -- build
...
Built "/nix/store/16n1klx5cxkjpqhrdf0k12npx3vn5042-nixos-system-baryum-23.11pre-git"

$ nix run nixpkgs#nix-diff -- \
  /nix/store/yyw9rgn8v5jrn4657vwpg01ydq0hazgx-nixos-system-baryum-23.11pre-git \
  /nix/store/16n1klx5cxkjpqhrdf0k12npx3vn5042-nixos-system-baryum-23.11pre-git \
  --color always | less
```

Also, in lieu of `nix-diff`, a nice summary of version changes can be produced with:

```bash
nix run nixpkgs#nvd -- diff \
  /nix/store/yyw9rgn8v5jrn4657vwpg01ydq0hazgx-nixos-system-baryum-23.11pre-git \
  /nix/store/16n1klx5cxkjpqhrdf0k12npx3vn5042-nixos-system-baryum-23.11pre-git \
```

## TODOs

- [ ] Make sure nginx gets reloaded when SSL certs gets updated.
