Hmm, I got this warning, which seems harmless but unexpected:
Processing triggers for initramfs-tools (0.129) ...
update-initramfs: Generating /boot/initrd.img-4.9.0-2-amd64
W: initramfs-tools configuration sets RESUME=UUID=30db89e8-91f2-44ee-a8fa-61e5855ead41
W: but no matching swap device is available.
I: The initramfs will attempt to resume from /dev/nvme0n1p4
I: (UUID=30db89e8-91f2-44ee-a8fa-61e5855ead41)
I: Set the RESUME variable to override this.
My swap/resume settings are:
bjorn@miraculix:~$ cat /proc/swaps
