(cherry picked from commit 9a82dd87f7)
Reason: Importing devices from /dev/disk/by-id can prevent certain bugs
that lead to ZFS pool corruption, as mentioned in #11668.
That said, although this adds the option to import from /dev/disk/by-id,
I'm not yet changing the default import path in the stable channel
because possibly some block devices may not show up in /dev/disk/by-id,
causing a perfectly-working system to become unbootable. It's probably
safer to battle test the new default path in the unstable channel
instead, and let it become part of the stable channel as part of the
next NixOS release.
