Our system can utilize it's TPM2 to automatically decrypt. This can be done because the bootchain is secure and it's a bit tedious to enter an encryption password everytime the system boots up.
First off the packages `clevis` and `tpm2-tools` have to be installed:
```
# <apk add tpm2-tools>
$ <nix-shell -p clevis>
```
> Not yet doable (but will be don't worry ;) )
Now bind our LUKS volume to TPM with clevis:
If `home-manager` was installed correctly then it should have also installed both `clevis` and `tpm2-tools`. This allows for the binding of the LUKS volume to TPM with clevis:
```
# clevis luks bind -d /dev/<disk2> tpm2 '{"pcr_bank":"sha256","pcr_ids":"0,1,5,7"}'

Clevis can be envoked again if you have made any changes to secureboot or system and it doesn't automatically decrypt the disk.

First find the keyslot clevis is using and then "regen" the key:

It should now work again.

Nix can be used to manage your `$HOME` with `home-manager`. First install `home-manager` through:

Now that Nix is up and running utilize the `home.nix` that comes with the [config files](https://docs.bijl.us/alpine-desktop-setup/post-install/config-files/) to set up our home for us. But before initialising `nix` make sure that you set the correct `<username>` in `home.nix` which is located in `~/.config/home-manager`. Then after changing that simply run this command:
