Bug#804438: systemctl disable --now fails for aliased D-Bus services

[Michael Biebl]

Package: systemd
Version: 227-2
Severity: normal

systemctl disable --now foo.service is supposed to stop and disable a
service (there is also an equivalent enable --now command).
I just tried that with firewalld and got:

# systemctl disable --now firewalld
Synchronizing state of firewalld.service with SysV init with /lib/systemd/systemd-sysv-install...
Executing /lib/systemd/systemd-sysv-install disable firewalld
insserv: warning: current start runlevel(s) (empty) of script `firewalld' overrides LSB defaults (2 3 4 5).
insserv: warning: current stop runlevel(s) (0 1 2 3 4 5 6) of script `firewalld' overrides LSB defaults (0 1 6).
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
Failed to stop dbus-org.fedoraproject.FirewallD1.service: Unit dbus-org.fedoraproject.FirewallD1.service not loaded.


The firewalld service is not stopped as a result

firewalld.service has

[Install]
WantedBy=basic.target
Alias=dbus-org.fedoraproject.FirewallD1.service

systemd/systemctl seems to stop the service via the aliased name and we
remove the symlink beforehand. Seems to me, that systemctl should
actually try to stop firewalld.service, and not
dbus-org.fedoraproject.FirewallD1.service.

I haven't checked yet if this is an downstream bug (due to our
systemd-sysv-install script) or something which needs to be fixed
upstream.

So I'm filing this against our bug tracker for now.

We should probably add an autopkgtest for that :-)
