Ok, yes. Sorry, I did not express it correctly. I meant that base-files
is not responsible for ensuring that /run/lock exists "at all times".

As you rightly point out, there is indeed an attempt to ensure
that those directories exist after the very first install by debootstrap,
and this is done before /run becomes a ramdisk and before the first
reboot. I guess this is precisely your case.

What I would like to know is exactly what changed *elsewhere* so that
this code, which apparently used to work before, is not working anymore.

So: What is the parent directory which does not exist? It's /run ?
This directory belongs to base-files (try dpkg -L base-files).

Should it not be created by debootstrap when unpacking base-files?

BTW: I have not upgraded to trixie myself yet in my Desktop computer,
but I can use a virtual machine to test. Could you please explain exactly
how to reproduce the error? No need to post your script, only a *minimal*
case that shows the error.

Thanks.
