Hi,
I have a Raspberry Pi 3 Model B Rev 1.2 with Debian BullsEye on it, I
want to upgrade to Bookworm. Changing the kernel my main concern is
that the device name of the NIC will change from "eth0" to something
like "enp2s0...".
If 'raspi-firmware' is installed, it should be safe.
Check the file '/boot/firmware/cmdline.txt', it should contain the entry
'net.ifnames=0'.
I performed the upgrade and it was flawless. :)
I checked that "cmdline.txt" contains "net.ifnames=0" and it was, so the
interfaces have keep the old names as also explained in the wiki page ¹
