The scripts are more or less automated if you’re installing in a particular fashion. They’ll ask for user input along the way for configuring/customising certain things. What isn’t covered is a setup with multiple vdevs or UEFI or musl, but if you want these things you’ll probably be able to patch the scripts accordingly and perhaps these options could be accommodated in a future version.

The scripts live here: https://gitlab.com/emacsomancer/full-zfs-and-full-luks-encryption-on-void-linux , where you’ll find additional instructions and information.

(I do recommend using the Ubuntu Live ISO as your installer ‘host’ for ease and reduction of the installation time: the ‘host’ for the installation doesn’t really matter: basically it’s just being used to run the initial cryptsetup for the LUKS partition and initial ZFS pool creation and the host for the Void chroot. The Ubuntu Live CD has ZFS baked in, so you don’t have to wait twice(!) for DKMS to build ZFS modules.)

Using ZFS for the entire system, from / to /home to /boot also has the advantage of not requiring you to decide how much space to allocation ahead of time. With /boot on a separate partition, I’ve sometimes encountered issues of running out of space on /boot because of maintaining multiple kernels, or else having to massively overshoot in terms of how much space to give to /boot. A full ZFS install avoids this issue, and allows for easy snapshots of the /boot directory.

ZFS is a great file-system if you care about your data. ZFS is most impressive file-system, and it has a number of other wonderful features aside from data-integrity, and once you’re used to it, you’ll want it everywhere. For instance, the ‘default’ lz4 compression is effectively ‘free’, in terms of CPU usage (minor CPU hit for dealing with compression is offset by the need to process smaller chunks of data), and can be significant: on my root dataset (dozer/ROOT/system) I’m currently getting 1.79x compression: so 22.7G of logical data is written in 13.6G, and even my dataset full of PDFs has a more modest 1.03x compression ratio, but this means I save over 3G.

ZFS 0.8.0 also brings with it native encryption. I’ve not chosen to use this at the moment, as LUKS makes a full-disk setup easier at this point, but native encryption could be used in conjunction with LUKS encryption (potentially useful if, say, you want to backup up particular ZFS datasets to a remote and not entirely trusted machine:– natively encrypted ZFS snapshots can be sent without decrypting the data).

All of these various features, such as compression and encryption can be enabled per dataset, which allows for great flexibility. After suffering bit rot, which filtered through and rendered pointless my carefully maintained versioned backups, I really don’t like trusting my data to any other file-system.
