I'm fairly sure this has been fixed for a couple of months at
least. Unless it's reproducible with a current d-i image, I'm
fairly certain we've fixed it.
(There also won't be any logs really worth looking at I'm afraid;
it's all down to a single conditional in the initscripts postinst.
Which is skipped entirely if /run already exists, which is what
happens when base-files provides it during initial install after
it was fixed.)

The problem here is that both are correct--in different circumstances--
and it's very difficult to know after the fact that it's "wrong", so
you are correct that fixing it is hard. In fact, automated switching
can't be done during an upgrade due to in-use files etc., which is
why initscripts does it early during boot and why it can't be done in
We could possibly check if /run is a symlink *and* we're not in a chroot
during bootup and print a warning if present. But it will need some
careful consideration--e.g. it might legitimitely be this way on e.g.
GNU/Hurd, and it's not really "wrong" to manually configure it this way
on Linux, either.
