Public bug reported: When my system booted, it failed to create a /dev/disk/by-partuuid link for one partition (/dev/nvme0n1p11) that means that ceph is unable to start up (the relevant osd looks for /var/lib/ceph/osd/ceph-388/journal which is a symlink to /dev/disk/by- partuuid/d2ace848-7e2d-4395-a195-a4428631b333 which doesn't exist). See the shell outputs below:

I think this is related to this upstream issue: https://github.com/karelzak/util-linux/issues/361 ...this is quite a serious bug, as it's causing unrelated software (ceph) to break.
