Did an update "apt update && apt dist-upgrade" on my PBS an got
Code: 
update-initramfs: Generating /boot/initrd.img-6.8.12-8-pve
I: The initramfs will attempt to resume from /dev/dm-0
I: (/dev/mapper/pbs-swap)
I: Set the RESUME variable to override this.
Running hook script 'zz-proxmox-boot'..
Re-executing '/etc/kernel/postinst.d/zz-proxmox-boot' in new private mount namespace..
No /etc/kernel/proxmox-boot-uuids found, skipping ESP sync.
Couldn't find EFI system partition. It is recommended to mount it to /boot or /efi.
Alternatively, use --esp-path= to specify path to mount point.

did the same update at least once a month since about a year, never got messages like this, normally I get the message about a new kernel and I should reboot as soon as possible, what I did.

Now I do not know what will happen if I do a reboot, will that kill my PBS or can I ignore it, or what else should I do

UUID of nvme0n1p2 should be set in /etc/kernel/proxmox-boot-uuids
( UUID is displayed using lsblk -f )
To allow kernel update stored in partition nvme0n1p2


Only kernel update seems ignored.
