the only intrusive change in this new sysvinit release is the move
of the control FIFO from /dev/initctl (version 2.88) to /run/initctl
(version 2.89). After update it's not possible to talk to the running
init daemon.
Adding a sysmlink between the two locations doesn't work, because the
symlink would overwrite the real FIFO at /run/initctl upon another
install of 2.89.
The best way to solve this issue is to restart the system after update
by running
/etc/rc.shutdown
