Package: depthcharge-tools

Severity: normal

Hello,

while updating a testing system here, apt emitted the following output:

	Processing triggers for initramfs-tools (0.142) ...
	update-initramfs: Generating /boot/initrd.img-6.9.12-amd64

	Cannot build depthcharge images when no board is specified.
	Not booted with depthcharge, so ignoring that.

This warning was introduced with python3.12, up to now the right thing
happens:

	uwe@taurus:~$ python3.12
	Python 3.12.4 (main, Jul 15 2024, 12:17:32) [GCC 13.3.0] on linux
	Type "help", "copyright", "credits" or "license" for more information.
	>>> '\d'
	<stdin>:1: SyntaxWarning: invalid escape sequence '\d'
	'\\d'

To suppress the warning, either use raw strings (r'\d') or properly
quote the backslash ('\\d').

Best regards
Uwe
