when i run command:
pveversion

i get this output:
pve-manager/8.3.4/65224a0f9cd294a3 (running kernel: 6.5.13-5-pve)

but i thought 8.3 can/should run on kernel 6.8??

when i do
>>> apt update
>>>apt dist-upgrade
it also does not increase the kernel version. all is up to date.

i dont have any pinned kernel:

>>> proxmox-boot-tool kernel list
Manually selected kernels:
None.
Automatically selected kernels:
6.5.13-5-pve

so,
question 1: i wonder if this is OK or if i should go out of my way* to increase the kernel to 6.8???

*out of my way, because my boot partition is 235M, with only the current kernel installed,
/dev/nvme0n1p2 235M 106M 118M 48% /boot
when i would run a kernel upgrade, the update-initramfs step tries to write the vm-linuz-6.8 file to the /boot folder and would increase the space used right until it fails with error: no space left on device.

the 4 options i see:
- look if its possible to compress the kernel image
- look if its possible to move the existing kernel-image to another location/usb drive, so it is temporarily deleted and available if i need to recover something.
- move the files from the /boot partition to the root / and change fstab? although best practise is to keep boot separate partition.
- look if its possible to increase partition (with gparted?)

question 2: am i missing any other options / change the order of options to consider?

Welcome to the Proxmox forum, devale!

Usually pinning a kernel version is only recommended if newer kernel versions break the system for some non-mitigable reason. For Proxmox VE 8.3, the kernel 6.8 and 6.11 are the supported ones [0], so it's also recommended to upgrade if possible. Else, you're missing out on security and bug fixes that are only shipped to those series.

I think increasing the ESP partition would be your best bet, as yours is quite small. Make sure to make a backup of it in case that anything goes wrong and also have a rescue USB or something similar (e.g. Proxmox VE ISO, grml).
