[debhelper-devel] Bug#894510: debhelper: Because it is listing tmpfiles in systemd's only, conf overriding is not working

[Seyeong Kim]

Package: debhelper
Version: 9.20160115ubuntu3
Severity: normal
Tags: d-i

In autoscripts/postinst-init-tmpfiles, There is TMPFILE containing conf in systemd pkg only.
Then if there is 00rsyslog.conf from rsyslog pkg. and installing or upgrading systemd

/var/log's permission is 755(which is default) not 775(which is in 00rsyslog.conf)
overriding doesn't work when upgrading.

Please refer to below LP
ubuntu lp bug : https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1748147

removing TMPFILE from autoscripts/postinst-init-tmpfiles solves this issue.
e.g. change like below
systemd-tmpfiles --create #TMPFILES# >/dev/null || true
to
systemd-tmpfiles --create >/dev/null || true

and removing related code from dh_installinit maybe needed
e.g. below kind of part
        if (compat(10) && !$dh{NOSCRIPTS}) {
                # Include postinst-init-tmpfiles if the package ships any files
                # in /usr/lib/tmpfiles.d or /etc/tmpfiles.d
                my @tmpfiles;
                find({
                        wanted => sub {
                                my $name = $File::Find::name;
                                return unless -f $name;
                                $name =~ s/^\Q$tmp\E//g;
                                if ($name =~ m,^/usr/lib/tmpfiles\.d/, ||
                                        $name =~ m,^/etc/tmpfiles\.d/,) {
                                        push @tmpfiles, $name;
                                }
                        },
                        no_chdir => 1,
                }, $tmp);
                if (@tmpfiles > 0) {
                        autoscript($package,"postinst", "postinst-init-tmpfiles",
                                "s,#TMPFILES#," . join(" ", sort @tmpfiles).",g");
                }
        }

Is there any reason that TMPFILE list is there?
