I did a kind of bisect, because just looking at diffs I couldn't spot when the /var/spool/postfix/dev directory stopped being created.
What I found is: 3.9.1-4: creates /var/spool/postfix/dev 3.9.1-5: does NOT create /var/spool/postfix/dev, leading to the rsyslogd error about not being able to create the log socket in that dir. The debian/configure-instance.in diff shows this cp command now commented: +## ldaps needs this. debian bug 572841 (Mar-2010) +# let's omit this for now (in Dec-2024) for new installs and see what happens +# Having device nodes in /var causes numerous issues +# If anything, it can be bind-mounted from actual /dev, +# or better yet, just use proxy: map types. +# Might as well remove existing dev/*random from old chroot +#cp -a -n --parents /dev/random /dev/urandom . 2>/dev/null || : Maybe that was the only thing still in dev (the random devices), and now nothing else creates the dev directory.
