If you're going to be using NVMe, make sure you use a power-fail safe
version; I've already had one instance where ext4 failed to mount
because of a corrupted journal using an XPG SX8200 after the Honeycomb
Serror'd, and then I powered it down after a few hours before later
booting it back up.

EXT4-fs (nvme0n1p2): INFO: recovery required on readonly filesystem
EXT4-fs (nvme0n1p2): write access will be enabled during recovery
JBD2: journal transaction 80849 on nvme0n1p2-8 is corrupt.
EXT4-fs (nvme0n1p2): error loading journal
