#### Notes
We use slightly different options than the official guide. Most notably, `atime` is disabled as it has detrimental effect on performance and unnecessarily increases write operations. `compression` is changed from `lz4` to `zstd` as it has much better compression ratio than `lz4` while still maintaining good performance. We did not specify the encryption type here as `aes-256-gcm` is already the default with openZFS >= 0.8.4.

We specify compatibility=openzfs-2.1-linux to make sure that updates will not make the system unbootable in the future.
