Execute the following script from the root of the haccfiles directory on a NixOS-based host (otherwise initrd secrets and therefore the encrypted boot **will** break).
|
||
|
|
|
||
|
|
```sh
|
||
|
|
nix build -f . deploy.$hostspec
|
||
|
|
./result $action
|
||
|
|
```
|
||
|
|
|
||
|
|
`$hostspec` can be replaced by any hostname or group name. To find out wich groups exist, evaluate the expression `lib.attrNames groups` in the context of the top-level default.nix.
|
||
|
|
|
||
|
|
`$action` can be one of:
|
||
|
|
- switch: make the configuration the boot default and activate now
|
||
|
|
- boot: make the configuration the boot default
|
||
|
|
- test: activate the configuration, but don't make it the boot default
|
||
|
|
- dry-activate: show what would be done if this configuration were activated
|
||
|
|
|
||
|
|
It is recommended to run a dry-activate first, and if any of the changes mentioned have a chance of interrupting access to the server, executing a test and only once that succeeds a switch.
