[Pkg-sysvinit-devel] Bug#740459: Infinite loop reloading dbus service

[Erich Schubert]

Package: sysv-rc
Version: 2.88dsf-51
Severity: important

Hi,
Todays upgrade to unstable went into an infinite loop.
It may be related to the libc upgrade, but I can't tell for sure.
The system runs into an infinite loop reloading services, also
on "dpkg --configure -a":

insserv: Note: sysvinit service dbus is shadowed by systemd dbus.service,
Forwarding request to '/bin/systemctl --quiet --no-reload enable dbus.service'.
Synchronizing state for dbus.service with sysvinit using update-rc.d...
Executing /usr/sbin/update-rc.d dbus defaults
insserv: Note: sysvinit service dbus is shadowed by systemd dbus.service,
Forwarding request to '/bin/systemctl --quiet --no-reload enable dbus.service'.
Synchronizing state for dbus.service with sysvinit using update-rc.d...
Executing /usr/sbin/update-rc.d dbus defaults
... repeat.

It appears as if update-rc.d decided to call into insserv, insserv into
systemd, and systemd to call back into update-rc.d; repeat.

By adding an "exit 0" into the insserv_updatercd function of update-rc.d,
I was able to break this loop, and run dpkg --configure -a successfully.

Please add a safeguard against cyclic invocation of update-rc.d. Thanks.
