## Two stage update
The configuration is split into two parts to allow for two stage updates to conserve space
on storage-limited systems.
To run a two stage update do:
```shell
$ sudo NIX_LIGHTWEIGHT=1 nixos-rebbuild switch
$ reboot
```
then:
```shell
$ sudo nix-collect-garbage --delete-old
$ sudo nixos-rebbuild switch
```
