ZFS unlock at boot

25 February 2021, 01:22:34

I've been messing around with this for awhile but havent gotten anywhere. I run Arch with a ZFS root, but they have some extra initcpio systemd based hooks that prompt for a key. I tried to recreate these multiple ways but I guess im not doing it right.

Then I thought, why not just edit /etc/defaults/zfs and add ZPOOL_IMPORT_OPTS="-l", so it will prompt for a key automatically at import! That also didnt work. Maybe you have to do something special to allow prompting for user input in an initcpio hook? Not sure. Does anyon have a good solution that currently works well?

Also, does anyknow know how native zfs encyption compares to a LUKS encrypted ZFS device? I thought for awhile LUKS was supposed to be fast but not if thats changed. Thanks!
