Bug#1040445: udev creates wrong symlink from rule after upgrade to bookworm
In Debian 11.
root@imager:~# cat /etc/deb*ver*
11.8
root@imager:~# head -n 13 /etc/udev/rules.d/10* | tail -n 2
KERNEL=="sd?3", SUBSYSTEM=="block", ATTR{size}=="60028928", \
SYMLINK+="AY", OWNER="root", GROUP="root", MODE="700"
root@imager:~# ls -ld /dev/A*
lrwxrwxrwx 1 root root 4 Oct 22 07:00 /dev/AY -> sdb3
# That, ^, is the correct result.
In Debian 12.
root@imager:~# cat /etc/deb*ver*
12.2
root@imager:~# head -n 23 /etc/udev/rules.d/10* | tail -n 2
KERNEL=="sd?3", SUBSYSTEM=="block", ATTR{size}=="60028928", \
SYMLINK+="A1", OWNER="root", GROUP="root", MODE="700"
root@imager:~# ls -ld /dev/A*
lrwxrwxrwx 1 root root 4 Oct 22 06:53 /dev/A1 -> sda5
# That, ^, is the wrong result. /dev/sda has no ATTR{size}=="60028928".
Simple tests similar to these reported by Karl and I are likely to
produce failures in short order.
Failure of salient features impairs the appeal of Debian. With
removable storage routinely depending upon udev, successful operation
really should be verified before a new Debian is released.

Bug#1040445: udev creates wrong symlink from rule after upgrade to bookworm
I'm not up on the steps to do to get the debug (if you can list the command(s) to run?). BUT - After the last reboot which has 252.12-1~deb12u1 I saw lrwxrwxrwx 1 root root 9 2023-08-17 16:29 ttyUSB-nut -> gpiochip0 Which is wrong - So I unplugged and replugged the cable and looked again and see: lrwxrwxrwx 1 root root 15 2023-08-23 11:57 ttyUSB-nut -> bus/usb/001/003 Which is also wrong...

Package: udev
Version: 252.11-1
Severity: normal
Upgraded to bookworm and a working udev rule no longer creates correct symlink.
The rule:
ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", ATTRS{serial}=="AJV9MKOY",
SYMLINK+="ttyUSB-nut",GROUP = "nut", MODE="0666"
The resulting symlink
ll /dev/ttyU*
crw-rw-rw- 1 root nut 188, 1 2023-07-05 18:36 /dev/ttyUSB1
lrwxrwxrwx 1 root root 15 2023-07-05 18:36 /dev/ttyUSB-nut ->
bus/usb/001/010
The symlink should be - and was to /dev/ttyUSB1
Can you still reproduce the issue with 252.12?
If so, could you provide a verbose debug log of systemd-udevd?
