Try a netdev in the fstab options?

Are you sure nofail and nolock are a good choice?

Repeat the apt update?

Just done an update on my Daedalus workstation, worked fine.

I do not see any advantage from using openrc, runit, s6 ... whatever. They promise a lot, but I do not get their benefits.

Another thought: 4G is about the max a file can get on a fat32 partition?

Well, my workstation is a new installation (multiboot, paralell to a working Chimaera) of an early Daedalus preview before the release, no upgrade. Simple netinstall, fixed IP, just basic system utilities. AFAIK I just checked the resolv.conf, and did not need to change it. Manual installation of xorg, lightdm and cinnamon with --no-install-recommends, and everything else just as I needed it. No network manager at all.

connman isn't installed on my workstation, it just has LAN:

# apt list connman
Auflistung… Fertig
connman/stable 1.41-3 amd64
connman/stable 1.41-3 i386

I had no need for any network management here.

And I haven't manipulated anything regarding any symlink to /etc/resolv.conf, just entered my local ethernet router's IP.

Well, I have looked at two of my PCs with Daedalus: as well on my Ryzen workstation as on my travelling laptop I have a file /etc/resolv.conf, no symlink. And the entry in the file points to my local ethernet router IP as DNS (I am working with fixed IP adresses).

On the laptop I have the Gnome network manager installed to be able to switch between LAN and Wifi and Home and away.

Yes, I am running 6.10 now on Daedalus.

Maybe its related to the older version of the ext file system. Don't know how they do maintain the ext3 module it in the kernel. I would change that to ext4.

I am on ext4 since its available. I don't see any reason not to switch.

@alexkemp: kernel updates are handled by the (meta)-package linux-image-amd64.

When this package is installed from the main branch, you will automagically receive the main line kernel updates. When this package is installed from the bpo branch (apt -t daedalus-backports install linux-image-amd64), you will get the bpo kernel updates.

Security updates are a separate story.

When you only install a dedicated kernel image from bpo, you won't get updates.
