Hi everyone,
I saw that the post was followed, but unfortunately without any suggestions from you.
Anyway, my question probably should have been shorter, like:
Because, if I'm not mistaken, since Bullseye, the cmdline.txt has been stripped of the init= parameter with the resize counterpart
At this point, I opted for the following workaround,...but without completing my search for a solution.
I can assure you that the search was arduous; I generated many different images using pi-gen, and many days were wasted.
But in the end, I got there.
In the official documentation, I found no information on how a parameter in config.txt is used.

what mechanism on the Raspberry Pi in the Trixie distribution triggers the filesystem resize procedure?
Because, if I'm not mistaken, since Bullseye, the cmdline.txt has been stripped of the init= parameter with the resize counterpart
Code:
Bullseyecmdline = console=serial0,115200 console=tty1 root=ROOTDEV rootfstype=ext4 fsck.repair=yes rootwait init=/usr/lib/raspberrypi-sys-mods/firstbootCode:
Trixie (new)cmdline = console=serial0,115200 console=tty1 root=ROOTDEV rootfstype=ext4 fsck.repair=yes rootwait resizeAt this point, I opted for the following workaround,
Code:
# 1. Expand the partition to 100% of the disksudo parted /dev/mmcblk0 resizepart 2 100%# 2. Inform the kernel of the new sizesudo partprobe /dev/mmcblk0# 3. Grow the filesystem to fill the expanded partitionsudo resize2fs /dev/mmcblk0p2# 4. Remove 'resize' from cmdline (resize_early no longer does this)sudo sed -i 's/ resize//' /boot/firmware/cmdline.txt# 5. Verifydf -h /lsblkI can assure you that the search was arduous; I generated many different images using pi-gen, and many days were wasted.

What is the parameter?
Try to guess. I can only tell you that in my experiments, I started from my own consolidated config.txt file for Bullseye.
