Bug#851747: sysvinit-utils: drop Essential flag

[Andreas Henriksson]

FYI I've filed https://bugs.debian.org/954306 to track the
potential adjustment of the Priority: field, which seems to be
the majority of the discussion in this bug report.

I'm about to upload an NMU of sysvinit which drops the 'Essential: yes'
from sysvinit-utils - but still keeps 'Priority: required' unchanged
(and closing this bug report while doing so) for now.

Regards,
Andreas Henriksson
