 When installing Debian I used [this guide](https://libreboot.org/docs/gnulinux/encrypted_debian.html) in particular, while also encrypting /boot (named boot thus with the resulting full name lvm/matrix-boot, size a couple of hundreds MB). The guide uses LUKS->LVM->Partitions, thus everything is encrypted. You don't need to install GRUB since it is already on the libreboot ROM (if you're using the GRUB payload), however, using a local GRUB makes it possible to [change GRUB config](https://libreboot.org/docs/gnulinux/grub_cbfs.html) without reflashing ROM. But reflashing ROM can be done in the OS.
 If you don't encrypt /boot the default GRUB-scripts works better, i e it boots automatically, at least until the scripts are improved upon.
